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%.

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%。
