摘要

采用大变形弹性有限元法

借助MSC.Marc有限元软件

建立了昆明钢铁公司双机架紧凑式可逆炉卷轧机轧制过程的二维模型

对C45(0.43%～0.49%C)钢的2 mm×1200 mm带钢轧制平直度进行模拟。对带钢沿宽度方向上的应力分布进行三维模拟

得出上、下工作辊的辊径比对带钢平直度的影响。结果表明

当辊径比为420/418.5时

带钢的平直度最佳。

Abstract

Two dimensional models of rolling process of two-stand Steckel mill at Kunming Iron and Steel has been established using heavy reduction elastic-plastic finite element method (FEM) by finite element software MSC. Marc to simu> late the flatness of 2 mm x 1 200 mm rolled strip of steel C45(0. 43% -0. 49%C). And 3-dimension simulation of stress distribution along strip width direction has been carried out to get the effect of upper/lower roll diameter ratio on strip flatness. Results showed that as roll diameter ratio was 420/418. 5

the strip flatness was optimum.
