fig. 1 shows a flowchart of a control method of the hot rolled strip thickening rolling in the embodiment of the present application.

As shown in FIG. 1, the control method for the thickening rolling of the hot rolled strip at least comprises steps 110 to 160.

The following will describe the steps 110 to 160 shown in fig. 1 in detail:

in step 110, a slab to be rolled is obtained and divided into a first sub-slab, a second sub-slab and a third sub-slab.

In the application, the slab to be rolled is obtained, the slab to be rolled can be set as a mother slab, the mother slab is divided into three sub-slabs, namely a first sub-slab, a second sub-slab and a third sub-slab, the lengths of the first sub-slab, the second sub-slab and the third sub-slab can be set to be the same slab length, the lengths of the first sub-slab, the second sub-slab and the third sub-slab can also be set to be different slab lengths, and the slab lengths can be set according to actual needs.

With continued reference to fig. 1, in step 120, the first and second sub-slabs are assigned non-shear marks and the third sub-slab is assigned a shear mark.

In the application, before the slab to be rolled does not enter the roughing mill, the non-shearing marks can be set for the first sub-slab and the second sub-slab of the slab to be rolled through the PLC control system, the shearing marks can be set for the third sub-slab of the slab to be rolled, and the theoretical coil diameter of the strip steel coil corresponding to the slab to be rolled can be set.

With continued reference to FIG. 1, in step 130, historical rolling parameters of a rolling mill are obtained, the historical rolling parameters being used to direct the rolling mill to roll.

In the application, the historical rolling parameters of the rolling mill are obtained, wherein the historical rolling parameters can comprise rolling parameters corresponding to rolling of the rolling mill for rolling the strip steel with various thicknesses in the rolling period of the rolling mill, the rolling parameters corresponding to the strip steel with large thickness can be used as reference values, and the rolling parameters corresponding to the strip steel with small thickness can be obtained through improvement to a certain extent. And if the historical rolling parameters are empty, controlling the rolling mill to roll based on the rolling parameters corresponding to the strip steel with the highest thickness.

With continued reference to fig. 1, in step 140, the rolling mill is controlled to roll based on the historical rolling parameters for each sub-slab of each slab to be rolled and the historical rolling parameters are updated.

With continued reference to fig. 1, in step 150, when the sub-slab reaches the winding interval setting position, it is determined whether the sub-slab carries a no-shear flag.

In this application, the winding section setting position may be set according to actual needs.

With continued reference to fig. 1, in step 160, if the sub-slab carries a no-cut flag and there is a slab-tracking record, the slab-tracking record is cleared and the information of the sub-slab is updated to the slab-tracking record.

In the application, if the sub-slab carries the non-shearing mark and the slab tracking record exists, it is indicated that there is one sub-slab in the coiling process or after the coiling process, the coiling machine can only track one slab at a time, so that the tracking record of the previous sub-slab needs to be cleared before the sub-slab is tracked in real time, and the tracking information in the slab tracking record at least includes the position and the length of the sub-slab in the coiling interval.

In one embodiment of the present application, the method further comprises: giving a plate blank number to the plate blank to be rolled, wherein the plate blank number is used for identifying the plate blank in the rolling state at present; and giving a plan number to the sub-slab of the slab to be rolled, wherein the plan number is used for identifying the sub-slab in the rolling state at present.

In the present application, each slab to be rolled is assigned a slab number, each sub-slab of each slab to be rolled is assigned a plan number, and each slab to be rolled is assigned three plan numbers.

For example, a slab number may be given to each slab to be rolled in the production order starting from a natural number 1, one slab to be rolled for each natural number, with one roll period as one cycle. When one roll period is over, a new roll period is started, and a plate blank number is given to each plate blank to be rolled again from a natural number 1. The latter plate number can also be continued with the former plate number according to the production sequence.

For example, each sub-slab of slabs to be rolled may be given a letter ABC or XYZ as a plan number, a or X representing a first sub-slab, B or Y representing a second sub-slab, and C or Z representing a third sub-slab.

In one embodiment of the present application, the method further comprises: judging whether the strip steel corresponding to the slab to be rolled is subjected to shearing treatment or not; if the strip steel corresponding to the slab to be rolled is sheared, updating the slab number in the rolling state at present; judging whether the strip steel corresponding to the sub-slab is coiled or not; and if the strip steel corresponding to the sub-slab is coiled, updating the plan number of the sub-slab in the rolling state at present.

In the application, judging whether the strip steel corresponding to the slab to be rolled is subjected to shearing treatment or not; and if the strip steel corresponding to the slab to be rolled is sheared, updating the slab number in the rolling state at present. For example, when the strip steel corresponding to the slab with the slab number 020 is sheared, the slab number of the slab currently in the rolling state is 021, and the slab number currently in the rolling state is updated to 021.

For example, when the strip steel corresponding to the sub-slab having the slab number 020 and the plan number X is wound, the slab number 020 of the slab currently in the rolled state is described, the plan number Y is updated, and the plan number Y of the sub-slab currently in the rolled state is updated.

In one embodiment of the present application, the method further comprises: and if the sub-slab carries the shearing mark, controlling the flying shearing equipment to shear the sub-slab.

In one embodiment of the present application, the method further comprises: if the sub-slab carries the non-shearing mark and the slab tracking record does not exist, updating the information of the sub-slab to the slab tracking record until the next sub-slab reaches the set position of the coiling interval.

In the application, if the sub-slab carries the non-shearing mark and the slab tracking record does not exist, it is indicated that the former sub-slab is being sheared or is located after shearing, the coiling machine can only track one slab at a time, after the former sub-slab is sheared, the computer control system can clear the tracking information in the slab tracking record, and then the slab tracking record does not need to be cleared again, the sub-slab can be tracked in real time directly until the next sub-slab reaches the set position of the coiling interval.

In one embodiment of the present application, the controlling the rolling mill to roll based on the historical rolling parameters and updating the historical rolling parameters includes: determining target parameters required by the rolling mill to roll the strip steel corresponding to the sub-slab based on the historical rolling parameters; and controlling the rolling mill to roll the sub-slab based on the target parameters, and taking the target parameters as new historical rolling parameters.

In the application, regarding each sub-slab of each slab to be rolled, the historical rolling parameters are used as reference values, rolling parameters corresponding to the strip steel with one lower grade thickness are obtained through improvement to a certain extent, the rolling mill is controlled to roll, and the rolling parameters corresponding to the strip steel with one lower grade thickness are used as new historical rolling parameters.

In one embodiment of the present application, the method further comprises: judging whether the strip steel corresponding to the sub-slab is a target strip steel or not; if the strip steel corresponding to the sub-slab is the target strip steel, updating the historical rolling parameters based on the rolling parameters corresponding to the sub-slab, and taking the updated historical rolling parameters as target rolling parameters; and controlling the rolling mill to roll a new slab to be rolled based on the target rolling parameters.

In the application, whether the strip steel corresponding to the sub-slab is a target strip steel is judged, if the strip steel corresponding to the sub-slab is the target strip steel, the target strip steel can also be expressed as a main rolling material, the historical rolling parameter is taken as a reference value, the rolling parameter corresponding to the target strip steel is obtained through improvement to a certain extent, the rolling parameter corresponding to the target strip steel is taken as a new historical rolling parameter, the new historical rolling parameter is taken as a target rolling parameter, the rolling mill is controlled to roll the new slab to be rolled based on the target rolling parameter to obtain the main rolling material, the historical rolling parameter can be not updated before the corresponding rolling period is finished, and the rolling mill can continuously use the historical rolling parameter for rolling.
