摘要

为了改善1420 UCM冷连轧机轧制硬质薄规格镀锡板时轧制力偏大以及实物板形质量较差的情况,通过理论分析结合有限元模拟和现场试验,揭示了问题产生的原因,确定了相应的解决问题的技术思路。运用基于有限元模拟的辊型设计方法和软件,研制了新的工作辊端部辊型。生产应用结果表明,该工作辊端部辊型能够有效减轻压靠,取得良好的使用效果,板形缺陷出现的概率由原来的33.3%下降至5.2%。

Abstract

In order to improve the higher actual roll force and worse quality of the sheets shape with hard thin specification tin plates in 1420 UCM cold continuous rolling mill,theoretical analysis with FEM method and field experiment were applied. The reasons to those problems are revealed and the technological solutions to those problems are determined. On the basis of the FEM analysis and roll profile design software,a new polynomial curve of the working roll profile was proposed. Practical applications showed that the forced-contract was efficiently alleviated,obtaining good applicative effectiveness. The probability of plates defect occurs from 33.3% originally down to 5.2% .
