【摘要】 表面形貌是冷轧带钢表面质量的重要指标。本文针对高强钢平整轧制过程的特点,首先建立了二维的轧制区接触弧长度和平整轧制力计算模型,进而结合轧辊表面粗糙峰对带钢的压入、犁沟以及挤压作用,建立了综合考虑轧辊与带钢的粗糙峰接触、轧制力、轧辊与带钢相对滑动位移的平整轧制过程带钢表面形貌生成模型。研究了高强钢平整轧制过程带钢表面形貌的变化过程、影响因素与影响规律。更多还原

【Abstract】 The surface topography played an important role in surface quality of cold-rolled steel strip. According to the character of high-strength steel strip temper rolling, contact arc length model and roll force model were built. Combining the pressing-in furrowing and squeezing of asperities of work roll on steel strip, a model for the generation of surface topography was established considering asperities contact, roll force, relative sliding displacement between work roll and steel strip. The generation of surface topography of high strength steel strip and influence of process parameters during temper rolling were studied.更多还原
