摘要

通过建立棒材与轧辊的有限元模型

采用大型非线性有限元软件DEFORM-3D对GCr15轴承钢(/%:0.98C

0.54Si

0.34Mn

0.014P

0.002S

1.49Cr)300 mm×400 mm坯至ø130 mm棒材12道热连轧过程进行数值模拟

并与理论轧制力的计算值进行分析和对比。结果表明

数值模拟计算的轧制力接近生产实际测量的轧制力数据

两者相差不超过5%

尤其在粗轧阶段

两者相差不超过3%。

Abstract

The numerical simulation on 12 passes hot continuous rolling process from 300 mm X 400 mm bloom to ø130 mm bar products of bearing steel GCrl5 (/% : 0. 98C

0. 54Si

0. 34Mn

0. 014P

0. 002S

1. 49Cr) has been carried out by established finite element model for bar and roller and using large nonlinear finite element software DEFORM-3D

and is analyzed and compared to calculated values of theoretical rolling force model. Results show that numerical-simulation-calculated rolling force values is close to actual-measured ones in situ

the both difference is no more than 5%

especially in rough-rolling pass

that is no more than 3%.
