冷轧带钢表面粗糙度影响因素及控制策略
Influence factors and control strategy of cold rolled strip surface roughness
摘要
Abstract
Based on the worn surface topography of EDT work roll and the distribution of lubrication oil at rolling interface,surface roughness generation model in cold rolling was established by finite element method.The proposed model was of well forecasting ability,and could accurately predict the surface roughness of cold rolled steel strip.The relationship between steel strip surface topography and the minimum lubrication oil thickness was analyzed by means of simulation results.In addition,according to the established relationship and the distribution of oil film thickness,the effect of rolling parameter on the generation of strip surface topography was obtained.Control strategy aiming at control the surface roughness of steel strip by adjusting the rolling speed and reduction ratio in S5 stand was proposed.The results show that reaction ratio and rolling speed have a significant impact on the process of surface roughness transfer.关键词
