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.

Key words: silicon steel, cross section, load distribution, equal proportion convexity, roll shifting, roll wear
