摘要

通过建立的中厚板轧制压力3种预算温度模型对Q235钢（/%:≤0.22C，≤1.40Mn，≤0.35Si）200mm铸坯经12道次轧成20 mm板的各轧制道次轧制压力进行预算模拟

分析轧制温度模型对中厚板轧制压力预算精度的影响。结果表明

轧制温度模型通过轧件变形抗力对轧制压力预算精度产生影响

在中厚板轧制时

采用轧制温度模型△t=24Z[(t+273)/1000

]

/h对轧制压力进行预算的精度相对稳定且误差相对较小

为0.67%~12.41%。

Abstract

The rolling force of Q235 steel (/% ：≤0.22C

≤1.40Mn

≤0.35Si) at each pass rolled from 200 mm casting slab to 20 mm plate with 12 passes has been pre-calculated simulated by established three pre-calculated temperature models for medium-heavy plate to analysis the effect of rolling temperature model on prediction accuracy of rolling force for medium and heavy plate rolling. Results show that the rolling temperature model affects pre-calculated accuracy of rolling force by deformation resistance of stock; during medium-heavy plate rolling s the accuracy of rolling force pre-calculated by using rolling temperature model △t=24Z[(t+273)/1000

]

/h relatively constant and the relative error is relatively small

i. e. 0.67%-12.41%.
