摘　　要：横向厚差是硅钢产品板形的一项关键指标。针对目前UCM轧机轧制无取向硅钢横向厚差大的问题,以涟钢五机架UCM冷连轧机组为研究对象,建立了六辊轧机辊系的二维变厚度有限元模型。在结合现场实际情况的基础上进行大量仿真模拟计算,开发出可以实现高精度断面控制的ECC(Edge Crown Control)工作辊辊型曲线。现场试验结果表明:ECC辊型可以有效控制产品的边降,提高无取向硅钢产品的横断面控制精度。The transverse thickness deviation is a key to the shape accuracy of silicon steel products.In view of the large transverse thickness deviation of non-oriented silicon steel rolled by UCM mills in industrial production,this article takes the Liansteel five stands cold mills as the research object,and coupling model of six-high rolling mill,two-dimensional varying thickness finite element model is set up.ECC（Edge Crown Control）work roll contour is developed after large amount of simulating calculation to achieve high precision control technology of cross section.The experiments indicate that ECC work roll contour can control the edge drop of products and reduce the transverse thickness deviation of silicon steels,improving the cross-sectional precision control of silicon steel products and bringing huge economic and social benefits for enterprises.
