Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that the terms "first," "second," and the like are used merely to distinguish one description from another, and are not intended to indicate or imply relative importance.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 and 2 in combination, a continuous caster blank processing system 10 in an embodiment of the present application can be communicatively coupled to an electronic device 20. Continuous caster blank processing system 10 may include a plurality of processing apparatuses for processing a continuous caster blank. Different types of processing equipment typically process different caster blanks. The type and the number of the processing equipment can be set according to actual conditions. For example, the processing apparatus may be a heating furnace for heating the continuous casting slab, and the processing apparatus may be a rolling mill for rolling the continuous casting slab into a plurality of segments. Generally, the continuous caster slab processing system 10 may include a heating furnace and a rolling mill. Of course, the continuous casting machine blank processing system 10 may further include other devices, and the other devices may be set according to actual situations, which are not described herein again.

Understandably, the continuous casting billet is a metal raw material obtained after metal ore smelting, and is usually in a strip structure. For example, in the steel and iron industry, a continuous casting billet may be a long rolled steel. The continuous casting machine billet is a whole piece of raw material, the total weight is large (for example, the continuous casting machine billet of steel can be a long strip structure about 10 meters, and the total weight is about 10 tons), and the continuous casting machine billet generally needs to be cut by a rolling mill to be divided into small parts of raw material. The divided portions of the raw material may be processed by corresponding downstream processing equipment to obtain corresponding products (e.g., springs, steel plates, etc.).

The heating furnace can heat the continuous casting machine blank by burning energy media such as coal gas and coal. In other embodiments, the furnace may utilize electrical energy to heat the caster blank. The rolling mill may be used to roll one caster blank into a specified length of stock material for processing by downstream processing equipment. For example, a continuous casting slab of a strip structure may be rolled into multiple sections by rolling mills, and each rolled continuous casting slab is a raw material for manufacturing a corresponding downstream product (the raw material may be understood as a product obtained in a rolling process), and may be transported by a high-temperature resistant transport device (such as a conveyor belt) to a corresponding downstream processing device for processing. The specified length can be set according to practical situations, and is not particularly limited herein.

In this embodiment, the continuous casting slab processing system 10 can process a plurality of continuous casting slabs sequentially in a production line manner. For example, after being cooled to form a continuous cast slab, molten steel at a high temperature is first fed into a heating furnace of the continuous cast slab processing system 10, heated by the heating furnace, and then the continuous cast slab discharged from the heating furnace is transferred to a rolling mill, and rolled by the rolling mill, to cut the continuous cast slab into a plurality of pieces of raw materials. Each piece of raw material may be available for processing by downstream processing equipment. For example, downstream processing equipment may process each piece of raw material into downstream products such as steel plates, steel wires, springs, and the like.

In this embodiment, the electronic device 20 can be electrically connected to all processing devices of the continuous casting slab processing system 10, and can be used for detecting energy consumption data of each processing device. The electronic device 20 may comprise a processing module 21 and a storage module 22 coupled to each other, wherein the storage module 22 stores a computer program, and when the computer program is executed by the processing module 21, the electronic device 20 may execute the steps of the power consumption management method described below.

Of course, the electronic device 20 may further include other modules, for example, the electronic device 20 may further include a detection module for detecting energy consumption data of the processing equipment, and the energy consumption plan management apparatus 100. In other embodiments, the detection module may be a module separate from the electronic device 20. When the detection module is a module independent from the electronic device 20, the electronic device 20 may further include a communication module for establishing a communication connection with the detection module and acquiring the data detected by the detection module.

The detection module can be set according to actual conditions and can comprise one or more detection sensors. For example, when the energy consumption data includes gas usage and electricity usage, the detection module may include a gas meter for detecting the gas usage and an electric energy meter for detecting the electricity usage.

In this embodiment, the type of the continuous casting blank generally corresponds to the material of the continuous casting blank, and can be set according to actual conditions. For example, the continuous casting slabs can be classified into two types of stainless steel and common steel, and of course, in other embodiments, the types of the continuous casting slabs can be classified according to other manners, which are not specifically limited herein.

In the present embodiment, the processing module 21, the storage module 22, the detection module, and the energy consumption plan management apparatus 100 are electrically connected directly or indirectly to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The electronic Device 20 may be, but is not limited to, a Personal Computer (PC), a Mobile Internet Device (MID), a server, and the like.

Referring to fig. 3, an embodiment of the present application further provides an energy consumption plan management method, which can be applied to the electronic device 20, and each step in the method is executed or implemented by the electronic device 20. The method may comprise the steps of:

step S210, acquiring historical energy consumption data of the continuous casting machine blank processing system in a specified time and current energy consumption data of the continuous casting machine blank processing system in a current production period, wherein the historical energy consumption data comprises first energy consumption historical data of the continuous casting machine blank processing system in the specified time, second energy consumption historical data of the continuous casting machine blank processing system in the maintenance working condition and third energy consumption historical data of a material waiting working condition, the current energy consumption data comprises first energy consumption performance data of the continuous casting machine blank processing system in the current production period, second energy consumption performance data of the continuous casting machine blank processing system in the maintenance working condition and third energy consumption performance data of the continuous casting machine blank processing system in the material waiting working condition, and the specified time is longer than the time of the current production period;

step S220, determining energy consumption plan data representing the current production period according to the first energy consumption historical data, the second energy consumption historical data and the third energy consumption historical data, and the yield, the overhaul working condition duration and the waiting working condition duration of each type of continuous casting machine billet processed within the specified duration, wherein the energy consumption plan data comprise the usage amount of each type of energy medium;

step S230, when the difference value between any energy consumption performance data in the current energy consumption data and the similar energy consumption data in the energy consumption plan data is larger than or equal to the corresponding preset threshold value, recalculating the energy consumption plan data according to the difference value.

In this embodiment, the energy consumption planning data of the current production cycle is calculated by using the historical energy consumption data of the continuous casting machine billet processing system within the specified time length, so that the energy consumption planning data can be calculated in a refined manner. In addition, by analyzing the energy consumption plan data and the actual energy consumption data of the current production cycle, the energy consumption plan data is re-calculated under the condition that a certain condition is met (for example, the difference value between any energy consumption performance data in the current energy consumption data and the similar energy consumption data in the plan energy consumption data is greater than or equal to the corresponding preset threshold), and the effectiveness of energy consumption management and control is favorably improved.

The individual steps of the process are explained in detail below, as follows:

in step S210, the historical energy consumption data and the current energy consumption data may be acquired by the detection module. The collected historical energy consumption data and the current energy consumption data can be stored in a local storage medium (such as a hard disk) of the continuous casting machine billet processing system or the electronic equipment. The energy consumption data includes, but is not limited to, total usage of coal gas, total power consumption, total nitrogen usage, total oxygen usage, total compressed air usage, total water usage and other total usage of each type of energy medium, and individual consumption of coal gas, average power consumption, average nitrogen usage, average oxygen usage, average compressed air usage, average water usage and the like required for processing a specified type of continuous casting machine billet of a unit weight. The unit consumption can be the quotient of the total usage of each type of energy medium consumed for processing a given type of continuous casting slab divided by the total weight of the given type of continuous casting slab processed.

In this embodiment, in the historical energy consumption data, the first energy consumption historical data is energy consumption data detected during processing within a specified time period, the second energy consumption historical data is energy consumption data detected during maintenance conditions within a specified time period, and the third energy consumption historical data is energy consumption data detected during waiting conditions within a specified time period. In the current energy consumption data, the first energy consumption actual performance data is energy consumption data detected in a processing period in a current production period, the second energy consumption actual performance data is energy consumption data detected in an overhauling working condition period in the current production period, and the third energy consumption actual performance data is energy consumption data detected in a waiting working condition period in the current production period.

The historical energy consumption data within the specified time duration can be understood as that the time duration from the current date in the past dates is the historical energy consumption data within the specified time duration. Based on the method, the time of the collected historical energy consumption data is closer to the time of the current date, so that the timeliness of the historical energy consumption data is improved, and the influence on the timeliness of the data due to overlarge time span of the historical energy consumption data is avoided.

In this embodiment, the detection module is electrically connected to each processing device of the continuous casting machine billet processing system, and can collect energy consumption data of each processing device of the continuous casting machine billet processing system within a specified time period and total energy consumption data of the continuous casting machine billet processing system within the specified time period as historical energy consumption data. The specified time length is longer than the time length of one production period, and one specified time length can comprise a plurality of production periods and can be determined according to actual conditions, for example, the specified time length is the time length of one week, 15 days, 30 days and the like. The duration of one production cycle can be set according to actual conditions. Generally, the duration of each production cycle within the specified duration is fixed. For example, a production cycle may be 8 hours, 12 hours, 24 hours, etc. in duration.

The historical energy consumption data collected by the detection module can be divided into three categories, namely first energy consumption historical data during the process of processing a continuous casting machine billet within a specified time, second energy consumption historical data during the overhaul working condition and third energy consumption historical data of the material waiting working condition. Understandably, within a specified duration, the equipment status of each processing equipment of the continuous casting machine billet processing system can be divided into three categories, which are respectively: the method comprises the steps of showing the processing state of a continuous casting machine billet being processed, showing the maintenance state that processing equipment is in the maintenance working condition, and showing the waiting state that the processing equipment is waiting for loading. In the overhaul state and the material waiting state, part or all of processing equipment in the continuous casting machine billet processing system does not process a continuous casting machine billet, but the processing equipment or the continuous casting machine billet processing system still consumes energy.

The detection module can acquire energy consumption data aiming at the processing equipment in a processing state, a maintenance state and a waiting state, and then the acquired energy consumption data is used as one part of historical energy consumption data.

The current energy consumption data collected by the detection module can be divided into three categories, namely first energy consumption actual performance data during the process of processing a continuous casting machine billet in the current production period, second energy consumption actual performance data during the maintenance working condition and third energy consumption actual performance data during the waiting working condition.

In this embodiment, the electronic device may acquire the historical energy consumption data and the current energy consumption data from the storage medium in real time or periodically. The storage medium may be a hard disk in a continuous casting billet processing system or a storage medium such as a hard disk of an electronic device.

The electronic device may obtain the historical energy consumption data of the continuous casting machine billet once in each production cycle, or obtain the historical energy consumption data of the continuous casting machine billet once every day, and the mode of obtaining the historical energy consumption data may be set according to actual conditions, and is not specifically limited herein. In addition, the electronic device may obtain the current energy consumption data in the current production cycle in real time or periodically. For example, the interval duration for periodically acquiring the current energy consumption data may be set according to an actual situation, for example, the duration is 8 hours, 1 day, and the like.

In step S220, the first energy consumption history data may include usage amounts of each type of energy medium consumed for processing each type of continuous casting slab for a specified time period. The yield obtained for each type of caster blank processed may be the weight of the caster blank processed. The second energy consumption history data may include usage of each type of energy medium consumed by the entire continuous caster slab processing system during the service condition for a specified length of time. The third energy consumption history data may include usage of each type of energy media consumed during the material waiting condition for a specified duration. The consumption amount of each type of energy medium includes, but is not limited to, the usage amount of coal gas, the power consumption amount of electric energy, the usage amount of oxygen, the usage amount of nitrogen, and the like, and includes the total usage amount and the single consumption amount of each type of energy medium.

After the electronic equipment acquires the historical energy consumption data, the first energy consumption historical data, the second energy consumption historical data, the third energy consumption historical data and the yield obtained by each type of continuous casting machine blanks processed within the specified time length can be input into corresponding calculation models, and therefore energy consumption planning data representing the current production period can be obtained. The calculation model can be determined according to actual conditions, and can be used for determining energy consumption plan data of the current production cycle under three working conditions, namely a machining period, an overhaul working condition period and a waiting working condition period, wherein the energy consumption plan data are respectively first energy consumption plan data, second energy consumption plan data and third energy consumption plan data. The energy consumption plan data for each type may include a total usage amount of each type of energy medium in the current production cycle, or a single consumption amount of each type of energy medium. The unit consumption is the consumption of the energy medium consumed by processing the continuous casting machine billet with unit weight.

As an alternative embodiment, the yield includes the weight of the billet of the continuous casting machine to be processed, and the step S220 may include:

In this embodiment, the calculation models for different classes of energy consumption data may be different. For example, in the first energy consumption history data, the total usage amount of each type of energy medium and the unit usage amount of each type of energy medium during the processing of each type of continuous casting billet may be included. In the first energy consumption plan data, the total planned usage amount of each type of energy medium during machining in a single production cycle, and the planned usage amount of each type of energy medium consumed for machining a single continuous casting slab and the planned usage amount of the continuous casting slab for machining a unit weight in a single production cycle may be included. For example, in the current production cycle, the energy consumption plan data for processing a given type of caster blank may be: during the processing of a continuous casting slab of a specified type for a specified length of time, the total usage of each type of energy medium is divided by the number of continuous casting slabs of the specified type processed for the specified length of time.

In the current production cycle, the planned usage of each type of energy medium consumed to process a given type of caster slab may be: during the processing period of processing the continuous casting blank of the specified type in the specified time length, the total usage of each type of energy medium is divided by the total weight of the continuous casting blank of the specified type processed in the specified time length (the calculation mode of the energy consumption planning data is a calculation model). The specified type of the continuous casting blank can be set according to actual conditions, and for example, the specified type of the continuous casting blank can be any one of stainless steel and common steel.

For example, in the first energy consumption plan data, the gas plan amount (energy consumption plan data) for processing a continuous casting slab of a specified type per unit weight in the current production cycle may be the total usage amount of gas during processing divided by the total weight of the continuous casting slab of the specified type processed for a specified time period. The projected power usage for processing a given type of caster slab may be: the total power usage during the process of processing a continuous casting slab of a specified type divided by the number of continuous casting slabs of the specified type processed within a specified time period.

The second energy consumption history data may include a total usage amount of each type of energy medium, an average usage amount of each type of energy medium per unit time, and a usage amount of the energy medium distributed to process a unit weight of the continuous casting slab during the overhaul condition. For example, the second energy consumption history data may include, but is not limited to: the total usage amount and the total power consumption of the gas during the maintenance working condition, the average usage amount and the average power consumption of the gas per hour during the maintenance working condition, the usage amount and the power consumption of the gas for processing the continuous casting machine billet of unit weight and the like. The second energy consumption plan data may include a total planned usage amount of each type of energy medium, an average usage amount of each type of energy medium per unit time, and a planned usage amount of each type of energy medium distributed to process a unit weight of the slab (in this case, it is not necessary to distinguish a type of the slab to be processed).

In the second energy consumption historical data, the average usage amount of each type of energy medium in unit time is: during the maintenance working condition, the total usage of each type of energy medium is divided by the maintenance working condition duration to obtain a difference value.

In the second energy consumption plan data, the planned usage amount of each type of energy medium for processing a unit weight of a continuous casting slab may be: and in a specified time period, dividing the total usage of each type of energy medium during all the overhaul working conditions by the total weight of all continuous casting billets processed in the specified time period (the energy consumption planning data is calculated in a mode of a calculation model). The specified energy medium can be determined according to actual conditions. In the second energy consumption plan data, the total usage of each type of energy medium for one production cycle may be: the total usage of each type of energy media during all service conditions is divided by the number of production cycles in the specified time period over the specified time period.

For example, in the second energy consumption plan data, the energy consumption plan data of the gas distributed to process the continuous casting slab of the unit weight may be: and in the specified time length, dividing the total power consumption of the coal gas in all the overhauling working conditions by the total weight of all the continuous casting machine billets processed in the specified time length. The planned power consumption allocated to the continuous casting blank of the processing unit weight may be: the total power usage during all service conditions is divided by the total weight of all caster blanks processed within the specified time period over the specified time period.

Likewise, the third energy consumption history data may include total gas usage during the hold condition, total electricity usage, average electricity usage per hour, average gas usage per hour, and the like. In the third energy consumption planning data, the calculation manner of the energy consumption planning data of each type of energy medium is similar to that of each type of energy medium in the second energy consumption planning data, and is not described herein again. For example, in the third energy consumption historical data, the average usage amount of each type of energy medium in unit time is: and during the material waiting working condition, dividing the total usage of each type of energy medium by the time of the material waiting working condition to obtain a difference value.

As an optional embodiment, the current energy consumption data includes a total usage amount of each type of energy medium, an average usage amount of each type of energy medium in a unit time length, and a usage amount of each type of energy medium during each process of processing each continuous casting billet, a usage amount during a maintenance condition, and a usage amount during a waiting condition. Step S230 may include:

For example, in the first energy consumption performance data and the first energy consumption plan data, when a difference between a total usage amount of a specified energy medium in the first energy consumption performance data and a planned total usage amount of the specified energy medium in the first energy consumption plan data is greater than or equal to a first threshold, it indicates that there is an abnormality in the usage amount of the specified energy medium in the first energy consumption performance data. At this time, the total usage of the specified energy medium needs to be further analyzed. Generally, the total usage amount of the specified energy medium is composed of the usage amount of the specified energy medium for processing each continuous casting slab. When the total usage amount of the specified energy medium is further analyzed, a difference (i.e., a first difference) between the usage amount of the specified energy medium and the similar energy consumption data in the energy consumption planning data during the specified process of processing each continuous casting slab may be analyzed. If the difference value of the usage amount of the specified energy medium of one type is larger than or equal to the corresponding preset threshold value during the specified procedure of the continuous casting blank of the specified type, the specified type of the continuous casting blank is indicated, and the usage amount of the specified energy medium is abnormal during the specified procedure. Therefore, the abnormal use amount of various energy media on various continuous casting machine blanks and processing procedures can be finely positioned.

Wherein the specified process is typically performed by the corresponding processing equipment. The usage amount of the energy medium during the designated process for processing each continuous casting billet is as follows: and a processing apparatus for performing the specified process, the usage amount of the corresponding energy medium during processing of each continuous casting slab.

For the energy medium with abnormal usage, after the type and the processing procedure of the continuous casting machine blank with abnormal energy consumption are positioned, the similar energy consumption data in the energy consumption plan data can be optimized, and then the optimized energy consumption plan data is used for optimizing the corresponding procedure.

For example, in the first energy consumption performance data and the first energy consumption plan data, if the current energy consumption data indicates that the gas usage amount for processing the continuous casting machine billet of the specified type is greater than the gas usage amount in the energy consumption plan data, and the absolute value of the difference is greater than or equal to the corresponding preset threshold, the actual gas usage amount is greater, and the planned gas usage amount is smaller, the planned gas usage amount in the energy consumption plan data is adjusted according to the difference. For example, the amount of gas used during processing of a continuous casting slab of a specified type in a production cycle is increased according to the difference.

As an optional implementation, the method may further include: and controlling the operation condition of the continuous casting machine blank processing system according to the adjusted energy consumption plan data so that the energy consumption data of the continuous casting machine blank processing system after the operation condition is adjusted meets the set condition.

The setting condition may be set according to an actual situation, and may be a threshold range corresponding to the energy consumption data. The condition that the energy consumption data of the continuous casting machine billet processing system meets the set conditions can be understood that the usage amount of each type of energy medium of the continuous casting machine billet processing system after the operation state is modulated is within the threshold value range indicating that the usage amount meets the requirement.

For example, in the second energy consumption actual performance data and the second energy consumption plan data, if the gas usage amount during the maintenance working condition is greater than the gas usage amount during the maintenance working condition in the energy consumption plan data and the difference (the difference is an absolute value) is greater than or equal to the corresponding preset threshold value in the current energy consumption data, it indicates that the actual gas usage amount during the maintenance working condition is greater, and at this time, the planned gas usage amount may be maintained unchanged, and the gas usage amount during the maintenance working condition is reduced according to the difference (for example, the flow rate of gas combusted by the heating furnace is reduced, or the duration of the maintenance working condition is shortened), so that the difference between the adjusted gas usage amount and the gas usage amount in the second energy consumption plan data is smaller than the corresponding preset threshold value. If the gas usage amount in the current energy consumption data is less than or equal to the gas usage amount in the energy consumption planning data, the actual gas usage amount is small, and at this time, adjustment is not needed.

For example, in the second energy consumption actual performance data and the second energy consumption plan data, if the power consumption during the maintenance working condition in the current energy consumption data is greater than the planned power consumption of the maintenance working condition in the energy consumption plan data, and the difference (the difference is an absolute value) is greater than or equal to the corresponding preset threshold value, which indicates that the power consumption is greater, the actual power consumption during the maintenance working condition is reduced according to the difference (for example, the duration of the maintenance working condition is shortened); if the power consumption in the current energy consumption data is less than or equal to the power consumption in the energy consumption planning data, the actual power consumption during the maintenance working condition is smaller, and at the moment, adjustment is not needed.

For example, in the third energy consumption actual performance data and the third energy consumption plan data, if the gas usage amount during the waiting condition in the current energy consumption data is greater than the gas usage amount during the waiting condition in the energy consumption plan data, and the difference (the difference is an absolute value) is greater than or equal to the corresponding preset threshold value, which indicates that the actual gas usage amount is greater, the gas usage amount during the waiting condition is reduced according to the difference (for example, the flow of gas combusted by the heating furnace is reduced, or the duration of the waiting condition is shortened); if the gas usage amount in the current energy consumption data is less than or equal to the gas usage amount in the energy consumption planning data, the actual gas usage amount is small, and at this time, adjustment is not needed.

It should be noted that, in this embodiment, various preset thresholds (for example, a first preset threshold, a second preset threshold, a third preset threshold, and the like) may be set according to actual situations, and are not specifically limited herein. For example, the preset threshold value for each type of energy medium may be 5% of the energy consumption plan data for each type of energy medium.

In the processing and production process of a continuous casting machine billet processing system, if the actual situation in the production process deviates from the original planned production situation, if a material waiting time interval is not arranged in the original production plan, and the material waiting for production or other situations (such as maintenance) are required to be carried out due to the influence of the previous process in the actual production process, the current energy consumption data is obtained again, then the energy consumption plan data in the production cycle is re-checked, and the comparative analysis work is re-developed to verify whether the actual energy consumption in the production cycle is in a reasonable range (namely whether the set conditions are met).

As an optional implementation, the method may further include:

Understandably, when the difference value between any energy consumption data in the current energy consumption data and the similar energy consumption data in the energy consumption planning data is greater than or equal to the corresponding preset threshold value, it indicates that the similar energy consumption data is abnormal, and a prompt needs to be sent. The output prompt message can be displayed through a display screen or sent out through a loudspeaker. Through the sent prompt information, the manager can conveniently and quickly position the abnormal energy consumption data and timely optimize the abnormal energy consumption data. For example, step S230 is performed again to optimize the energy consumption data of the continuous caster slab processing system.

As an optional implementation, the method may further include:

In this embodiment, each processing device may be provided with a sensor for detecting the remaining amount of the energy medium. The electronic device can acquire the remaining amount of the energy medium from the sensor in real time as the current remaining amount. The preset residual quantity can be set according to actual conditions. The target processing equipment can be determined according to actual conditions and can be one or more processing equipment in a continuous casting machine billet processing system. Different energy mediums may correspond to different thresholds. When the remaining amount of the energy medium is less than or equal to the preset remaining amount, it generally means that the remaining amount of the energy medium stored in the processing device is small and needs to be replenished. At the moment, the prompt information is sent, so that the situation that the surplus of the energy medium is insufficient can be found by a manager in time, and the energy medium can be supplemented in time. For example, when the residual amount of the gas in the heating furnace is insufficient, a prompt can be given in time.

Based on the design, the automatic formulation of an energy consumption plan in one production period of a steel rolling process, and the real-time calculation and comparative analysis of the energy consumption performance index after the production period is finished can be realized. In addition, the planned energy consumption is adjusted or the energy consumption of the working condition is adjusted, so that the production data of the index planned value is close to the actual production performance as much as possible, and the reasonability and effectiveness of energy consumption management and control are improved.
