AI Technical Summary
During hot rolling, the high temperature at the tail end of the slab leads to a low thickness hit rate at the tail end of the finished product, and traditional control methods cannot effectively solve the problem of thin tail thickness.
By acquiring information on the steel grade of the strip and the rolling speed of the finishing mill, the strip ejection speed and rate are determined, and the strip ejection process at the tail end is controlled to keep the tail end temperature within a preset temperature threshold. Combined with the bite speed compensation of the roughing mill and the roll gap control of the finishing mill, the temperature and thickness of the tail end are optimized.
It improves the hit rate of strip thickness at the tail end, enhances the consistency of thickness at the head and tail, improves the quality of finished products, and avoids downstream welding difficulties and strip breakage risks.
