摘要
概况介绍了国内某钢厂热轧轧线的基本情况,重点针对某条轧线支撑辊在使用过程中经常出现断辊现象,从支撑辊材质和制造工艺的双优化升级,到通过超声波检测分析、研究并判断支撑辊辊颈断裂的位置。结合长期的检测跟踪,指导现场支撑辊的使用。
This paper introduces the basic situation of the hot rolling line of a steel plant in China,focusing on the phenomenon that the backup roll of a rolling line often breaks in the use process,from the double optimization and upgrading of the backup roll material and manufacturing process to the analysis,research and judgment of the fracture position of the backup roll neck through ultrasonic testing.Combined with long-term detection and tracking,it guides the use of on-site backup roll.
