Application of steel grade compensation in thickness control of cold-rolled high strength steel
There was anobvious discrepancy between the actual thickness of the high strength steel produced on the pickling tandem cold rolling mill and the thickness measured by an X-ray thickness gauge,and the quality accident of thickness deviation was prone to occur.The reason of the thickness discrepancy was analyzed,and an offline steel grade compensation method of the thickness was deduced.After it was applied in production,the thickness deviation of the high strength steel measured by the X-ray thickness gauge was less than 0.01 mm,which met the requirement of the thickness precision for the high strength steel.
