摘要/Abstract

摘要： 以某1420mm带钢冷连轧机为原型，采用三维弹塑性有限元法对UCM轧机冷轧过程进行了模拟，分析了不同板形调控机构对轧制压力分布的影响.结果表明:在工作辊弯辊作用下，轧制压力在带钢边部的峰值消失且在中部逐渐增加，使马鞍型三维分布变为凸型分布；中间辊弯辊对轧制压力的影响相对较小，基本没有改变其分布形式；中间辊横移消除了轧制压力在带钢边部骤增的趋势，使其在接触变形区的分布更平缓.三者对轧制压力的影响程度:工作辊弯辊>中间辊横移>中间辊弯辊，这与其调控功效对比结果一致，表明板形调控机构通过影响轧制压力分布来改变带钢板形的工作机理.

Abstract: Based on a 1420mm tandem cold rolling mill in a domestic plant， rolling processes in an UCM mill were simulated by 3D elastic-plastic finite element method(FEM). Effects of work roll bending(WRB)， intermediate roll bending(IRB)and intermediate roll shifting(IRS)on the rolling pressure were investigated. The results showed that peak values of rolling pressure near the strip edge disappear and the central rolling pressure increases with increasing of WRB， and the saddle-shaped distribution of rolling pressure becomes a convex-shaped distribution. Rolling pressure is hardly affected by IRB， and its distribution form is not changed basically. The sharply increased trend of rolling pressure near the strip edge is eliminated due to IRS， and the steep pressure field becomes smooth. Rankings of effects of the three actuators on rolling pressure are: WRB>IRS>IRB， which is in good agreement with the comparison of actuator efficiencies， and it shows that the working mechanism of controlling strip shape is achieved by affecting the rolling pressure distribution.

Key words: UCM mill, elastic-plastic FEM, work roll bending(WRB), intermediate roll bending(IRB) and intermediate roll shifting(IRS), rolling pressure
