冷轧硅钢生产过程中经常遇到孔洞缺陷造成断带,分析孔洞缺陷导致断带的原因,结合森吉米尔轧机先进的板形控制技术,提出板形目标曲线动态设定控制方法,并成功应用到20辊森吉米尔轧机上。试验结果表明,板形目标曲线动态设定控制方法对减少缺陷断带,稳定轧制状态具有非常显著的效果。 Cold-rolled silicon steel often encounters holes in the production process, resulting in broken belts, hole defects caused by the reason of broken belt, combined with Sendzimir mill advanced shape control technology, put forward the shape of the target curve dynamic setting control method, and successfully applied 20 rolls on Sendzimir mill. The experimental results show that the method of dynamic setting control of plate-shaped target curve has a very significant effect on reducing the breakage of the defect and the steady rolling state.
