Abstract:High strength container plate is a steel used for containers with the yield strength above 700 MPa and the tensile strength above 800 MPa, and it is generally cold- rolled strip. For this kind of high strength steel, the problems of the edge cracking at the tail end, the strip running deviation and strip breaking, and the strip shape abrupt changes have frequently occurred in the tandem cold rolling process. Based on the systematic analysis of the above problems, the measures such as the U- type coiling in the hot rolling line, the tandem automatic tilting control and the automatic compensation function of the head and tail bending roll in hot rolling production line were put forward, which can effectively solve the problems of edge cracking, strip breaking and ill flatness in the rolling process of high strength container plate. And it achieved good practical results.
