[0002] The pickling and skin pass mill adopts three-section loop configuration to organically connect the inlet section, pickling process section, outlet section and rolling mill section.

The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0040] The implementation details of the technical solutions of the embodiments of the present application are described in detail below:

[0041] First of all, it should be noted that the acid rolling loop control scheme proposed in the present application can be applied to the related technical field of acid rolling loop. By obtaining the position information of N groups of loops in the acid rolling mill group, the target loop sequence that is not in the preset position range is found, that is, one or more groups of loops in the acid rolling mill group that are not in the preset position range are found. Adjust the position of the loop corresponding to the target loop sequence found to make the position information of the loop corresponding to the target loop sequence within the preset position range. Further, by adjusting all loops with position error problems to the preset position range, the position error and zero loss problems of the loops in the acid rolling mill group can be solved.

[0042] According to one aspect of the present application, an acid rolling loop control method is provided, Figure 1 For the flowchart of the acid rolling loop control method according to the embodiments of the present application, the acid rolling loop control method at least includes steps 110 to 130, which are described in detail as follows:

[0043] In step 110, the position information of N groups of loops in the acid rolling mill group is obtained.

[0044] Specifically, N can be an integer greater than 0, and the acid rolling mill group can have one or more loops. By obtaining the position information of all loops in the acid rolling mill group, it is determined whether there is a loop with position error that is not within the specified range, that is, a loop that is prone to zero loss.

[0045] In step 120, if the position information of any one of the N groups of loops is not within the preset position range, the target loop sequence that is not within the preset position range is obtained.

[0046] In one embodiment of the present application, referring to Figure 2 , step 120 can be performed according to steps S1-S2:

[0047] Step S1: If the position information of any one of the N groups of loops is not within the preset position range, the target loop that is not within the preset position range is obtained from the N groups of loops.

[0048] Step S2: generating the target loop sequence based on the target loop.

[0049] In an embodiment of the present application, the target loop comprises one or more loops, and the generating the target loop sequence based on the target loop comprises:

[0050] If the target loop is one loop, the loop is taken as the target loop sequence.

[0051] If the target loop is a plurality of loops, the plurality of loops are taken as the target loop sequence.

[0052] Specifically, the preset position range can be set according to the original zero position of the piston. In the embodiment of the present application, the preset position range is that the deviation of the zero position of the piston does not exceed 3 cm. That is, if the deviation of the zero position of any one of the plurality of loops from the original preset zero position exceeds 3 cm, the loop is identified as a loop with a position error, and the loop is included in the target loop sequence.

[0053] In step 130, the positions of the loops corresponding to the target loop sequence are adjusted based on the preset position range, so that the position information of the loops corresponding to the target loop sequence is within the preset position range.

[0054] In an embodiment of the present application, the adjusting the positions of the loops corresponding to the target loop sequence based on the preset position range comprises:

[0055] The target loops corresponding to the target loop sequence are adjusted in position one by one based on the preset position range, so that the target loops are all within the preset position range.

[0056] Specifically, each loop in the target loop sequence is adjusted in position. After the deviation of the zero position of each loop from the original zero position does not exceed 3 cm, the position adjustment of all the loops with the zero position deviation is completed, so as to ensure the normal and stable continuous production of the mill train in the subsequent operation.

[0057] In an embodiment of the present application, the acid rolling loop control method provided by the present application can further comprise the following steps 140-150:

[0058] Step 140: obtaining the loop amount, the inlet speed and the outlet speed of the loop.

[0059] Step 150: performing loop filling synchronization based on the loop amount, the inlet speed and the outlet speed.

[0060] Specifically, the adjustment of the loop filling synchronization can be performed by acquiring the loop amount of the loop, the inlet speed of the loop and the outlet speed of the loop. When the loop filling synchronization is performed, the inlet speed of the loop is greater than the outlet speed of the loop. When the actual value of the loop amount of the loop is 0.2 m away from the set synchronization position value, the inlet speed is decelerated to the outlet speed. When the loop amount reaches the set value, the inlet speed and the outlet speed reach the synchronization, and the loop amount no longer changes.
