Edge drop control technique of silicon steel for UCM tandem cold rolling mills

  • 摘要: 以马钢四机架UCM酸洗冷连轧联合机组为研究对象,采用显示动力学有限元方法建立了六辊轧机辊系与轧件一体化有限元仿真模型.在分析其边降控制性能的基础上,提出通过调整UCM轧机中间辊窜辊位置控制带钢边降的方法.采用自主研发的适用于UCM轧机的U-EDC工作辊辊形,取得了硅钢边降≤5μm合格率由46.0%跃升到99.3%以上的显著生产实绩,在工作辊不能窜动的六辊轧机上成功实现边降控制.

     

    Abstract: Taking the d-stand PL-TCM cold rolling mill of Masteel as a research object, an explicit dynamic finite element method was adopted to build a combination simulation model for the roll stacks of the 6-high mill and silicon steel strips. Based on analyzing its edge drop control ability, the method of optimizing the intermediate roll shift position was proposed to reduce the edge drop of silicon steel strips. By using the U-EDC work roll contour which was self-designed and used to edge drop control for the UCM cold rolling mill, a remarkable production result was achieved that the qualification rate of silicon steel strips with the anaverage edge drop less than 5 μm increases from 46.0% to above 99.3%, and high precision shape control has been successfully accomplished in the 6-high mill without work roll shifting.
