In order to explain the technical means of the present application, the following description is given by way of specific examples.
Referring to fig. 1, a scene schematic diagram of a first application scenario of an automatic steel entering and exiting method for a heating furnace provided in an embodiment of the present application is shown. As shown in fig. 1, the first application scenario includes a heating furnace, a steel charging machine, a gate controller, a gate, a rough rolling device, a steel feeding roller way, a steel discharging roller way, a rolling line roller way, and a rough rolling entrance.
When automatic feeding and discharging of a heating furnace are realized, the number of steel blanks to be rolled on a steel discharging roller way can be detected firstly, the number of the steel blanks to be rolled is compared with the number of preset steel blanks on the steel discharging roller way, in order to ensure that the production line can operate efficiently, the number of the steel blanks to be rolled cannot be less than the number of the preset steel blanks, if the number of the steel blanks to be rolled is less than the number of the preset steel blanks, the steel blanks to be rolled on the steel discharging roller way can be determined to be absent at the moment, the steel discharging supplement of the heating furnace is needed, but the steel discharging condition of the heating furnace is related to the production state information on a steel production line, so after the number of the steel blanks to be rolled on the steel discharging roller way is determined to be less than the number of the preset steel blanks on the steel discharging roller way, the production state information on the steel production line is combined, and the heating furnace is controlled to perform automatic steel discharging.
And because the heating furnaces on most steel production lines usually adopt step-by-step steel feeding and steel tapping when steel enters and exits, after the heating furnaces automatically tap steel, available charging spaces in the heating furnaces are used for feeding steel, at the moment, the quantity information of steel billets charged into the heating furnaces can be determined according to the detected available charging space information of the heating furnaces and the operation parameter information of the heating furnaces, and the steel charging machines are controlled to charge the steel billets into the heating furnaces according to the quantity information (the steel billets are transported to the steel charging machines through steel feeding rollers).
It should be understood that, after the heating furnace heats the steel billet to obtain the steel billet to be rolled, the steel billet to be rolled can be transported to the rough rolling device through the tapping roller way, the rolling line roller way and the rough rolling inlet to be rolled.
It should also be understood that the gate controller in the first application scenario is used for receiving a switching signal of a terminal device to control the opening and closing of the gate, and the gate is used for controlling the time when the steel billet to be rolled enters the rough rolling device.
According to the embodiment of the application, the steel inlet and outlet amount and the time of the heating furnace are controlled by detecting the number of the steel blanks to be rolled on the steel outlet roller way and the available charging space information in the heating furnace and combining the production state information on the steel production line and the operation parameter information of the heating furnace, so that the working efficiency of the steel production line is improved.
Referring to fig. 2, a schematic flow chart of an automatic steel feeding and discharging method for a heating furnace of a steel production line according to a second embodiment of the present application is shown, where the automatic steel feeding and discharging method for a heating furnace is applied to the first application scenario shown in fig. 1. As shown in fig. 2, the automatic steel feeding and discharging method for the heating furnace may include the following steps:
The steel tapping roller way can be a roller way between the heating furnace and the gate in fig. 1, and a steel blank to be rolled of the steel tapping roller way can enter the rough rolling device to be roughly rolled after passing through the gate, so that a plurality of steel blanks to be rolled can be reserved on the steel tapping track, after the last steel blank to be rolled enters the rough rolling device, the next steel blank to be rolled on the steel tapping roller way can be immediately prepared to pass through the gate, and when the last steel blank to be rolled is roughly rolled, the next steel blank can be transmitted to the rough rolling device through the rolling line roller way through the gate, so that rolling seamless connection is realized, and time cost is saved.
In the embodiment of the application, if the number of the billets to be rolled on the steel-tapping roller table is less than the preset number of the billets, and the billets to be rolled cannot be timely transmitted to the rough rolling device, the rough rolling device idles, and time and power are wasted.
In a possible embodiment, the control of the automatic tapping of the furnace, in combination with the production status information on the steel production line, comprises:
if the production state information indicates that the steel production line runs normally, after the fact that the number of steel billets to be rolled on the steel rolling table is smaller than the preset number of steel billets is determined, a steel tapping instruction is sent to the heating furnace so as to control the heating furnace to carry out steel tapping operation according to the steel tapping instruction;
and if the production state information indicates that the steel production line has an operation fault, sending a steel tapping pause instruction to the heating furnace so as to control the heating furnace to stop steel tapping operation according to the steel tapping pause instruction.
In the embodiment of the application, if the production state information indicates that the steel production line runs normally, and the number of steel billets to be rolled on the steel rolling table is smaller than the preset number of steel billets on the steel rolling table, it is determined that the steel billets to be rolled need to be added on the steel rolling table to overcome the phenomenon that idling of a rough rolling device is easily caused and further time and power are wasted, and at the moment, a steel tapping instruction is sent to the heating furnace to control the heating furnace to tap steel according to the steel tapping instruction; if the production state information indicates that an operation fault occurs on the steel production line, the production line is a continuous goods conveying and carrying machine on a certain line, the operation fault occurs at one position, and the whole production line needs to be suspended for operation, so that if the production line has a fault, a suspended tapping instruction is sent to the heating furnace, and the phenomenon that a large number of steel blanks to be rolled on a tapping roller way are overlapped due to continuous tapping of the heating furnace is avoided.
In one possible embodiment, if the production state information indicates a steel product production line operation failure, a pause tapping instruction is sent to the heating furnace to control the heating furnace to stop tapping operation according to the pause tapping instruction, and the method comprises the following steps:
if the production state information indicates the operation fault of the steel production line, acquiring fault processing time corresponding to the operation fault;
and sending a steel tapping pause instruction to the heating furnace based on the fault processing time so as to control the heating furnace to stop steel tapping operation according to the steel tapping pause instruction until the fault processing time is finished.
The pause steel tapping instruction comprises fault processing time corresponding to the fault, and the fault processing time can be preset processing time according to the corresponding fault or processing time input by a user.
In the embodiment of the application, after the heating furnace receives the instruction of pausing the steel tapping, which comprises the fault processing time, the instruction can be executed to stop the steel tapping operation until the fault processing time is finished.
It should be understood that after the fault handling time is over, the terminal device should detect the production state information of the production line again, and when the obtained production state information indicates that the steel production line operates normally, the heating furnace is controlled to tap steel.
And 202, after automatic steel tapping, determining quantity information of steel billets to be filled into the heating furnace according to the available charging space information of the heating furnace and the operation parameter information of the heating furnace, and controlling a steel filling machine to automatically feed steel according to the quantity information.
In the embodiment of the application, if the idle step distance exists in the heating furnace, after one billet to be rolled is produced, the next billet to be rolled is far away from the steel tapping hole, and after the next billet to be rolled moves by a plurality of steps, the next billet to be rolled does not reach the steel tapping position, but at the moment, the available charging space is already arranged in the heating furnace, so that the steel tapping needs to be carried out after the steel is first put in, the rhythm of the steel feeding after the steel feeding is first put in is influenced, and the yield is restricted from being improved. Therefore, after the empty step (namely the available charging space) occurs in the heating furnace, the steel charging machine is controlled to charge the corresponding number of steel billets into the heating furnace in time, and the occurrence of the empty step of the heating furnace is reduced.
Because the operating parameters of the heating furnace have great influence on the quality of the produced billet to be rolled, after the available charging space in the heating furnace is determined, the operating parameter information of the heating furnace also meets the preset operating conditions, and then the steel filling machine can be controlled to fill the billet into the heating furnace according to the quantity information.
In a possible embodiment, the method for determining the quantity information of the billet steel charged into the heating furnace according to the available charging space information of the heating furnace and the operation parameter information of the heating furnace comprises the following steps:
and when the operation parameter information of the heating furnace meets the preset operation condition, determining the quantity information of the steel billets filled into the heating furnace according to the available loading space information of the heating furnace and the volume information of the steel billets.
The operation parameter information of the heating furnace may refer to the temperature in the furnace and the exhaust gas temperature of the heating furnace, and when both the temperature in the furnace and the exhaust gas temperature meet a preset operation condition (i.e., a preset temperature range), the quantity information of the steel billets to be loaded by the heating furnace may be determined according to the available loading space information (i.e., volume information) and the volume information of the steel billets.
In a possible embodiment, after controlling the heating furnace to perform the tapping operation according to the tapping instruction, the method further includes:
acquiring tail position information of a billet to be rolled passing through a gate;
if the tail position information indicates that the tail of the corresponding billet to be rolled reaches the inlet of the rough rolling device, the gate sends an opening instruction to control the gate to be opened, so that the next billet to be rolled can conveniently reach the rough rolling device through the gate;
and after the tail of the next billet to be rolled passes through the gate, sending a closing command to the gate to control the gate to be closed and waiting for the next opening command.
Wherein, a steel billet to be rolled exists on a rolling line roller way between the gate and the rough rolling device at most.
Illustratively, assuming that three steel billets to be rolled exist on a steel-tapping roller way, which are a first steel billet to be rolled, a second steel billet to be rolled and a third steel billet to be rolled, the tail position information of the first steel billet to be rolled is firstly obtained and can be obtained through a camera installed at the inlet of a rough rolling device, when the tail of the first steel billet to be rolled reaches the inlet of the rough rolling device, a gate is opened, the second steel billet to be rolled can be transported to the rough rolling device through a gate and a rolling line roller way, after the tail of the second steel billet to be rolled passes through the gate, the gate is closed, at the moment, only the second steel billet to be rolled exists on the rolling line roller way, and when the tail of the second steel billet to be rolled reaches the inlet of the rough rolling device, a gate controller receives an opening instruction again, controls the gate to be opened, and sequentially transmits the steel billets to be rolled on the steel-tapping roller way.
It should be understood that the gate can be used for ensuring the orderly transmission of the steel blanks to be rolled, and preventing the steel blanks to be rolled from entering the rough rolling device to cause the waste of raw materials when the steel production line fails.
After the steel billets to be rolled on the steel tapping roller way are determined to be smaller than the preset number of the steel billets on the steel tapping roller way, the lack of the billets to be rolled on the steel tapping roller way is determined, the production state information on a steel production line can be combined at the moment, the heating furnace is controlled to automatically tap steel, after the automatic tapping, the space step can appear inside the heating furnace, namely, available charging space exists, and therefore the quantity information of the steel billets to be charged in the heating furnace can be determined according to the available charging space information of the heating furnace and the operation parameter information of the heating furnace at the moment, the steel charging machine is controlled to automatically feed steel according to the quantity information, the steel charging amount and the steel discharging time of the heating furnace can be controlled according to the production state information on the steel production line and the operation parameter information of the heating furnace, and the work efficiency of the steel production line is further improved.
Referring to fig. 3, a schematic flow chart of an automatic steel feeding and discharging method for a heating furnace of a steel production line according to a third embodiment of the present disclosure is shown, where the automatic steel feeding and discharging method for a heating furnace is applied to a second application scenario shown in fig. 4, where the second application scenario includes two heating furnaces, a steel loader, a gate controller, a gate, a rough rolling device, a steel feeding roller way, a steel discharging roller way, a rolling line roller way, and a rough rolling inlet. As shown in fig. 3, the automatic steel feeding and discharging method for the heating furnace may include the following steps:
In the embodiment of the application, the heating time of the billets in at least two heating furnaces can be determined according to the time when the billets are loaded into the heating furnaces and the current time, and the heating furnace in which the billet with the long heating time is located can be determined to preferentially tap steel.
Illustratively, as shown in fig. 4 of the heating furnace 1 and the heating furnace 2, if the heating time of the billet in the heating furnace 1 is determined to be longer than the heating time of the billet in the heating furnace 2 by 1 times, the heating furnace 1 is controlled to preferentially discharge steel.
