摘要/Abstract

摘要： 根据低碳结构钢Q235(C≤0.20%)4300 mm中厚板现场轧制工艺,采用有限元软件ABAQUS/Explicit建立弹塑性有限元模型对展宽比1.70、精轧伸长率7.87的中厚板普通轧制过程和MAS(水岛平面形状控制轧制法)轧制过程分别进行了模拟计算,对不同变形阶段进行了对比分析。结果表明,MAS轧制法能明显改善中厚板轧后平面形状,其形状的改变量与MAS轧制段设置参数直接相关,对比不同参数下MAS轧制结果得出MAS轧制最优参数△L×△h为300×3。

Abstract: Based on works rolling process of 4300 mm medium-heavy plate of low carbon steel Q235 (C ≤0. 20% ) the elastic-plastic finite element model is established by using the finite element software ABAQUS/Explicit to simulate and calculate the general rolling process and MAS (Mizushima automatic plan view pattern control system) rolling process for medium-heavy plate with spread ratio 1. 70 and finishing rolling elongation 7. 87, and the comparative analysis on different deformation stages is carried out. Results show that the plane shape of rolled medium-heavy plate is obviously improved by using MAS rolling method, its changed value in shape is directly related to the setting parameters at MAS rolling stage, and the MAS rolling optimum parameter i. e. △L×△h= 300 x3 is obtained by comparing the rolling results using different MAS parameters.
