冷连轧机ESS辊型板形控制性能分析

Analysis on shape control performance of cold tandem mill with ESS roll profile

以某2 230 mm六辊五机架冷连轧机为研究对象,采用ABAQUS有限元软件平台建立了具有中间辊ESS辊型的三维非线性轧机仿真模型。通过数值模拟,分析了工作辊弯辊、中间辊弯辊和中间辊横移等板形调控手段综合作用下的板形控制域的变化规律。同时,系统研究了不同工作辊弯辊力、中间辊弯辊力和中间辊横移量等参数对带钢二次凸度和四次凸度的调控性能。现场应用结果表明,ESS辊型轧机对带钢板形和横向厚度均具有良好的控制作用。

Taking the six-high five-stand cold tandem mill of 2 230 mm as research object,the three-dimensional nonlinear mill simulation model with intermediate roll using ESS profile wase stablished through the ABAQUS finite element software platform. By numerical simulation,the variation law of the shape regulation region was analyzed under the combined action of shape control means including work roll bending,intermediate roll bending and intermediate roll transverse movement. Meanwhile,the control performance of different parameters including work roll bending force,intermediate roll bending force and intermediate roll transverse movement value to quadratic crown and quartic crown of the strip was researched systematically. The application results show that the mill with ESS profile has a good control effect on the shape and transverse thickness of the strip.
