The defect of transverse crack on surface is the folded mark vertical to rolling direction of steel belt and the defect of pickled SPHC product has been the main quality problem faced by production line since Rare Earth Steel Plate Co., Ltd. was put into production in commission, which seriously influences the yield and qualified rate. In the article, it is analyzed its mechanism, studied the effects of chemical components, coiling temperature, levelling process, decoiling temperature of pickling and deep bending roll on it as well as a series of related improvement measures are taken so that its occurrence rate is reduced significantly and the effects are better.
