Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, it shows a flow chart of an implementation of a processing method for supplementing net coke for a blast furnace provided by an embodiment of the present invention, which is detailed as follows:
in step 101, during tapping in front of the furnace, it is determined whether or not clean coke needs to be added after the tapping.
In the embodiment of the invention, the smelting process of the blast furnace can be monitored, when the tapping in front of the furnace is monitored, a judging step is triggered, whether the pure coke needs to be supplemented after the tapping is judged through the judging step, and whether the operation of supplementing the pure coke is carried out after the tapping is determined according to the judging result. Specifically, the determining step may use a change of the current tapping amount from the average of the previous tapping amounts as a determination basis, and determine that the net coke needs to be added after the current tapping when the tapping amount increased by the current tapping amount from the average of the previous tapping amounts is greater than a threshold.
Optionally, as shown in fig. 2, the step 101 may be implemented by:
and 204, if the current tapping amount is larger than the average tapping amount and the tapping amount difference value is larger than a first preset value, determining that the clean coke needs to be added after the current tapping.
In the embodiment of the present invention, the last designated time period refers to a preset time period until the current tapping, and the length of the time period may be designated in advance. For example, the last specified time period may be specified as the first 8 hours until the current tapping.
In the embodiment of the present invention, the difference between the tapping amounts is used to indicate the deviation degree of the tapping amount at this time from the average tapping amount corresponding to the last specified time period. The first preset value is a preset threshold value of the difference value of the iron tapping amount, wherein the first preset value is larger than the threshold value and indicates that the net coke needs to be supplemented, and the first preset value is not larger than the threshold value and indicates that the net coke does not need to be supplemented.
For example, the first preset value may be set to 10% of the average iron tapping amount corresponding to the last specified time period, or the first preset value may also be set to a fixed value, and the first preset value may be set according to actual situations, which is not limited herein.
In step 102, if it is determined that the net coke needs to be added after the current tapping, the net coke amount needed to be added after the current tapping is calculated.
In the embodiment of the invention, when tapping is carried out before the furnace, the current tapping amount is obtained and compared with the average tapping amount in the last specified time period, and when the comparison result shows that the current tapping amount is larger than the average tapping amount and the difference value between the average tapping amount and the average tapping amount is larger than a first preset value, the fact that the net coke needs to be added after the current tapping is judged, and the step of calculating the net coke amount needed to be added after the current tapping is triggered.
Specifically, the tapping quantity difference value can be converted into a net coke quantity according to the comprehensive coke ratio, and the net coke quantity required to be supplemented after tapping is determined according to the net coke quantity obtained by conversion.
In the embodiment of the invention, the comprehensive coke ratio refers to the quantity of coke converted from fuels such as coke, coal powder, heavy oil and the like consumed by a blast furnace for producing each ton of molten iron.
Optionally, the step 102 may include:
and A1, acquiring the comprehensive coke ratio of the blast furnace in the last appointed time period.
In the embodiment of the invention, the comprehensive coke ratio of the blast furnace in the last specified time period of the current tapping is firstly obtained. Illustratively, the above-mentioned integrated focal ratio may be obtained by the integrated focal ratio calculation formula:
wherein, KtotalRepresents the integrated focal ratio, Q, of the last specified time periodkRepresents the amount of coke dry consumed, Q, of the last specified time periodrRepresenting the coal dust consumption of the last specified time period,Brrepresents the replacement ratio of the injected fuel to the coke in the last designated time period, and P represents the pig iron production in the last designated time period.
And A2, calculating a first net coke amount corresponding to the tapping quantity difference value according to the comprehensive coke ratio.
In the embodiment of the present invention, after the integrated coke ratio is obtained, the difference in the amount of iron tapping may be converted into the first net coke amount indicating the net coke loss in the current iron tapping from the integrated coke ratio.
Optionally, the step a2 may include:
substituting the comprehensive coke ratio and the iron yield difference value into a preset first formula to obtain the first clean coke amount, wherein the first formula is as follows:
K1＝a×Pdif×Ktotal
wherein, K1Represents the first net coke amount, PdifRepresents the difference of the amount of iron, KtotalAnd a represents a preset first calculation constant.
In the embodiment of the present invention, the value range of a may be set according to the actual road condition, and the preferable value range is 16% to 19%. In practical application, the value range of a can be further optimized according to different silicon (Si) contents of pig iron (smelting material).
In an exemplary practical application scenario, when the silicon content of pig iron is greater than 0.4%, the furnace temperature is an upper limit furnace temperature, and the value range of a can be 16% -17%; when the silicon content of the pig iron is less than 0.2%, the pig iron is the lower limit furnace temperature, and the value range of a can be 18% -19%; when the silicon content of the pig iron is between 0.2 and 0.4 percent, the normal furnace temperature is adopted, and the value range of a can be between 17 and 18 percent.
And A3, determining the net coke amount required to be supplemented after the current tapping according to the first net coke amount.
In the embodiment of the invention, the first net coke amount represents the net coke loss of the current tapping relative to the average tapping amount of the last specified time period, and the first net coke amount can be directly used as the net coke amount required to be supplemented after the current tapping.
However, in practical applications, part of the net coke loss corresponding to the current tapping may also be caused by the top temperature change of the blast furnace, so that it is necessary to remove part of the net coke loss caused by the top temperature change of the blast furnace in order to obtain a more accurate net coke amount calculation result.
Optionally, the step 102 may include:
step B1, acquiring the average top temperature of the blast furnace in the last appointed time period;
step B2, acquiring the top temperature of the blast furnace during the current tapping;
step B3, calculating the top temperature variation of the top temperature of the blast furnace relative to the average top temperature during the current tapping;
in this embodiment, the top temperature of the blast furnace during the current tapping may be the current tapping time, or may be an average temperature of the time period of the current tapping time, for example, the top temperature of the blast furnace during the current tapping may be an average temperature of the current hour corresponding to the current tapping.
For example, if the last specified time period is specified as the first 8 hours of the current tapping, the average top temperature of the last specified time period may be: (T)1+T2+…+T8)÷8。
Then, the amount of change in the top temperature may be:
Tdif＝(T1+T2+…+T8)÷8-T0
wherein, TdifRepresents the amount of change in the top temperature, T1+T2+…+T8Indicates the sum of the top temperatures in the first 8 hours, (T)1+T2+…+T8) Div 8 represents the mean top temperature, T, of the first 8 hours0The top temperature of the blast furnace at this tapping is shown.
And B4, calculating a second net coke amount corresponding to the top temperature change amount according to the comprehensive coke ratio.
In the embodiment of the present invention, the amount of change in the top temperature of the blast furnace may be converted into the second net coke amount indicating the net coke loss corresponding to the change in the top temperature, based on the integrated coke ratio calculated as described above.
Optionally, the step B4 may include:
substituting the comprehensive coke ratio and the top temperature variation into a preset second formula to obtain a second clean coke amount, wherein the second formula is as follows:
K2＝b×Tdif×Ktotal
wherein, K2Represents the second net coke amount, TdifRepresents the amount of change in the top temperature, KtotalAnd b represents a preset second calculation constant.
In this embodiment, the second calculation constant b means the influence ratio of the top temperature of the blast furnace to the comprehensive coke ratio, and in a furnace condition, the top temperature of 100 ℃ influences 30 kg of the comprehensive coke ratio, and the value of the second calculation constant b can be 30%, namely 0.3.
Step B5, calculating a net coke amount difference between the first net coke amount and the second net coke amount;
and step B6, taking the net coke amount difference value as the net coke amount required to be supplemented.
In the embodiment of the invention, the second net coke amount corresponding to the change of the top temperature of the blast furnace is removed from the first net coke amount, and the obtained net coke amount difference value is used as the net coke amount required to be supplemented.
And in step 103, after the current tapping, performing an operation of supplementing net coke on the blast furnace according to the required supplemented net coke amount.
In the embodiment of the invention, after the net coke amount required to be supplemented is calculated, an instruction can be sent to a hoisting system of the blast furnace to instruct the hoisting system to supplement the net coke to the blast furnace after the current tapping so as to increase the fuel of the blast furnace and prevent the furnace temperature from decreasing.
Optionally, the step 103 may include:
adding the net coke amount of a first preset proportion in the net coke amount required to be added into the blast furnace at one time in a first specified time;
and continuously adding the net coke amount which is remained in the net coke amount required to be added and is not added in the net coke amount of the first preset proportion to the blast furnace within a first specified time after the first specified time.
In this embodiment, in order to prevent short-term excessive fluctuation of the furnace temperature that may be caused by the addition of the net coke and to maintain the furnace temperature curve stable, the amount of the net coke to be added may be added in several times. Namely, the net coke amount of a first preset proportion is added to the blast furnace at one time in a specified time (first specified time) after the tapping is finished; for example, the first predetermined proportion may be 50%. After the first specified time, the remaining net coke not supplemented is continuously supplemented to the blast furnace for a specified time period (first specified time period).
The first designated time and the first designated time period may be set according to actual conditions, and are not limited herein.
Therefore, whether the clean coke needs to be supplemented or not after the current tapping is judged when the tapping is carried out in front of the furnace, so that whether the furnace temperature is reduced or not due to the fact that excessive heat is possibly taken away because the tapping amount is high or not can be known in time; when the situation that the furnace temperature is reduced due to the change of the iron output amount is effectively reduced, the balance of the thermal system of the blast furnace is favorably ensured, and the occurrence of serious accidents such as furnace cooling and the like is reduced and even avoided.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
