钛合金棒材连轧变形过程分析及孔型优化设计

Deformation Process Analysis and Pass Optimum Design for Continuous Rolling of Titanium Alloy Bars

摘要:

在钛合金棒材热连轧机组“平三角-圆”孔型基础上，基于对轧制过程分析和有限元模拟，对现有的平三角孔型加以改进，形成改进型“平三角-圆”孔型系统，然后将Φ25 mm的TC4钛合金棒材在改进孔型后的八机架Y型轧机上连轧至Φ15 mm, 以求解决轧件出耳子、扭转、圆度差等问题，提高产品的尺寸精度

Abstract:

The existing flat triangle pass was improved in the "flat triangle-round" pass system of titanium alloy bar hot continuous rolling, based on analysis of rolling process and finite element simulation. Titanium alloy TC4 rod with Φ25 mm was rolled to that with Φ15 mm by the improved 8 stand tandem Y type rolling mill, aimed to solve the problems such as ears throughout the bar, twist and the poor roundness, and to improve the dimension precision of productions
