摘　　要：硅钢对横向同板差有严苛的要求,降低冷轧带钢的横向同板差,必须保证热轧硅钢来料凸度和楔形综合最小,热轧常规采用7机架CVC辊型轧制硅钢,然而硅钢对凸度和楔形的高要求和CVC机型特点,导致CVC辊型轧制硅钢存在诸多缺陷,为此应用硅钢大凹辊轧制技术,大凹辊辊型技术包括辊型设计和自由窜辊制度,实践表明采用大凹辊技术既能保证硅钢目标凸度,同时扩展硅钢轧制计划,改善轧制后期硅钢热轧边缘降。该技术为热轧凸度和楔度综合控制提供了指导。It has a strict requirement of transverse thickness difference for silicon steel. To reduce the transverse thickness deviation of the cold rolling strip,it must reduce the hot rolling silicon steel crown and wedge. 7-stands CVC rolling mills are conventionally applied to hot rolling of silicon steel.However,it has many defects for CVC mills to roll silicon steel as a result of strict requirements on strip crown and wedge and the characteristics of the CVC rolling mill. In order to solve this problem,the large crown roller technology was puts forward. Large crown roll technology includes roll shape designing and roll free shifting strategies. The results of simulations and experiments show that the technology of large concave roller can not only guarantee the silicon steel strip crown targets,but also extend the number of silicon steel in a rolling plan and improve the hot rolling strip edge drop in the end of rolling schedule. This technology provides guidance for the comprehensive controlling of silicon steel crown and wedge in hot rolling.
