摘要: 武汉钢铁有限公司CSP硅钢产量不断提升,由于同宽轧制的特点,硅钢断面不良的问题逐步暴露出来。针对目前存在的几种断面不良问题,通过优化原有西马克二级负荷分配的方案,从等比例凸度控制能力、窜辊及轧辊磨损上进行分析,发现工艺调整后不但满足板形良好条件并且在轧辊磨损、硅钢凸度、楔形的精度、断面控制上有了较大的提升。

Abstract: The output of silicon steel has been continuously improved in CSP plant of Wuhan Iron and Steel Co. Ltd.. Due to the characteristics of the same width rolling, the problem of poor cross section of silicon steel was gradually exposed. In viewing of the existing problem of the poor cross section, the control ability of equal proportion convexity, the roll shifting and the roll wear were analyzed through optimization of the original SMS two load  allocation plan. The results showed that the adjusted process can not only satisfy the condition of good steel plant shape but also get a great improvement on the roll wear, the steel crown, the wedge precision and the cross section control.
