以降低辊耗为目标的热轧平整机工作辊辊型设计

Roll Profile Design of Work Roll of Hot Rolling Temper Mill Aiming at Reducing Roll Consumption

为了降低工作辊辊耗、改善带钢板形质量,基于河钢唐钢2050 mm热轧平整机组的设备工艺参数,在Abaqus环境下建立了热轧平整机三维有限元模型。利用该模型计算了不同工作辊辊型下的辊间压力和带钢轮廓,结合平整过程的工艺特点和带钢凸度控制范围优化了工作辊辊型曲线。优化后的工作辊辊型经过现场应用,降低了工作辊辊耗的同时保证了带钢的板形质量。

In order to reduce the work roll consumption and improve the shape quality of strip,based on the process parameters of 2050 mm hot rolling temper mill in Tangshan Iron and Steel Co.,Ltd.,a three-dimensional finite element model of hot rolling temper mill was established in Abaqus environment.The model was used to calculate the inter roll pressure and strip profile under different work roll profiles,and the work roll profile curve was optimized according to the process characteristics of leveling process and strip crown control range.After field application,the optimized work roll profile reduces the work roll consumption and ensures the strip shape quality.
