摘　　要：轧辊是带钢生产的关键接触工艺装备,针对冷轧辊加工使用过程中存在的问题,从轧辊的磨削、轧辊的无损检测、轧辊的使用三个方面对生产过程中提高表面质量,降低生产成本,保证连续生产高效运行。轧辊的无损检测对冷轧板的轧制意义重大,尤其超声波检测。轧辊在线运行过程中降低轧制事故,根据轧辊粗糙度的衰减情况合理排程,提高镀铬辊的镀铬质量和优化支撑辊的边部倒角设计有利于降低轧辊消耗。Roller is the key contact technology equipment for strip production.In view of the problems in the process of cold roll processing,the surface quality is improved in the production process from the aspects of roll grinding,non-destructive testing of rolls,and the use of rolls,and the production cost is reduced to ensure continuous and efficient operation.Non-destructive testing of rolls is of great significance for the rolling of cold rolled sheets,especially ultrasonic testing.Rolling accidents are reduced during the on-line operation of the rolls.According to the attenuation of the roll roughness,the schedule is reasonable,the chrome-plating quality of the chrome-plated rolls and the edge chamfering of the support rolls are optimized to reduce the roll consumption.
