摘要

应用MSC.MARC三维热力耦合弹塑性大变形有限元法及其接触分析技术

仿真研究了Φ200mm H11芯棒钢热连轧过程。分析得出

降低末道次轧辊速度V

会增强道次间的堆钢程度;提高末道次轧辊转速V

会增强道次间的拉钢程度;可通过合理修正V

值来改善堆、拉钢关系以及轧制负荷变化和轧材宽展量

以提高圆钢成品精度。提出大规格圆钢热连轧过程应采用微堆钢轧制技术

以保持轧制力、力矩稳定和满足轧材尺寸精度要求。

Abstract

The hot continuous rolling process of 効00 mm Hll steel round bar for mandrel has been simulated and studied by using MSC. MARC 3- dimensional thermo-mechanical coupled elasto-plastic finite element method (FEM) and contact analysis technique. It is obtained by analysis that with decreasing last pass roller speed Vr the compression extent between passes increased; with increasing last pass roller speed V

the tensile extent between passes increased; therefore it is available to modify the relation between compression and tensile

the rolling load change and the widening extent of rolling products by change V

value in order to increase the product dimension precision. It is concluded that the light compression technology between passes shall be adopted during heavy round steel continuous rolling to keep the stability of rolling load and torque and guarantee the require

ment of product dimension precision.
