[0002] Automatic gain control (Auto Gain Control, AGC) rolling mills generally have multiple stands. During the production process, when one or more rolling mills break down, it often needs to be shut down for a long time to repair the failed rolling mills. Long-term downtime of the line, resulting in huge economic losses

Embodiment Construction
[0028] The inventor found through research that, for a rolling mill comprising 5 stands, since there are thickness gauge systems before and after the 1# stand and the 5# stand, it is impossible in the automatic gain control (Auto Gain Control, AGC) control system Alternatively, the rolling mill system cannot be separated from the 1# stand and the 5# stand for normal rolling. And the important spare parts in 2#, 3#, 4# racks are due to the high cost, there are no or few spare parts in actual production, such as important spare parts include: reduction box, main motor and so on. When this part of equipment is damaged, the production line can only be shut down for a long time, causing huge economic losses.
[0029] In view of this, the embodiment of the present application provides a rolling method, device, equipment, and storage medium. This method can realize that when the intermediate rolling mill fails, the rolling strategy of the continuous rolling mill can be updated so tha...

The invention discloses a rolling method, device and equipment and a storage medium. The method comprises the steps that whether a middle rolling mill except a head rolling mill and a tail rolling mill in a continuous rolling mill breaks down or not is detected; if one or more middle rolling mills break down, the current rolling strategy is updated based on the first operation parameter of the broken-down rolling mill, the second operation parameter of the previous rolling mill of the broken-down rolling mill in the strip steel operation direction and the third operation parameter of the next rolling mill of the broken-down rolling mill, the faulted rolling mill is a faulted intermediate rolling mill. According to the method, when the intermediate rolling mill breaks down, the rolling strategy of the continuous rolling mill is updated, so that the rolling mill which does not break down quickly returns to the normal operation state, and the downtime of a production line is shortened.
Description
technical field [0001] The invention relates to the technical field of iron and steel control, in particular to a rolling method, device, equipment and storage medium. Background technique [0002] Automatic gain control (Auto Gain Control, AGC) rolling mills generally have multiple stands. The long-term downtime of the line will cause huge economic losses. Contents of the invention [0003] The embodiment of the present application provides a rolling method, device, equipment and storage medium, which can quickly restore the normal operation state of the rolling mills that have not failed by updating the rolling strategy of the continuous rolling mill when the middle rolling mill of the continuous rolling mill fails. This reduces production line downtime. [0004] In the first aspect, the present invention provides the following technical solutions through an embodiment of the present invention: [0005] A rolling method, characterized in that it includes: detecting wh...
