酸轧工作辊表面剥落原因分析及预防

Analysis and prevention of surface peeling of work roll in PL-TCM

针对酸轧机组生产过程中频繁出现的轧机工作辊爆辊事故,从轧辊使用周期、生产过程控制、轧辊材质等方面进行了系统分析,找出了轧辊失效机理,并对轧辊失效过程进行了理论分析,据此制定了预防轧辊表面剥落的应对措施,有效预防和控制了轧辊爆辊事故的发生,使得爆辊事故发生率锐减,辊耗由2015年的1.12kg/t降低到0.49kg/t,辊耗损失大幅降低。

To the critical roll accident in the production process of PL-TCM,the systematic analysis on roll use cycle,production process control and roll material were carried out.The failure mechanism of roll was found and theoretically analyzed.The countermeasures to prevent the surface spalling of roll were developed,so the roll consumption decreased from 1.12kg/t in 2015to 0.49kg/t now,and the loss of roll was greatly reduced.
