从显微组织、性能、使用维护等方面对Cr12Mo1V1钢森吉米尔轧机工作辊端面掉块原因进行分析。结果表明,轧钢过程中工作辊端面升温、局部发生组织转变和工作辊端面硬度偏低是工作辊端面失效的主要原因。提高工作辊端面硬度和加强轧辊使用管理以后,工作辊的使用寿命得到提高。
From the microstructure, performance, use and maintenance of Cr12Mo1V1 steel Sendzimir mill work roll end surface of the reasons for the fall. The results show that the main reason for the failure of work roll face is that the temperature of working roll face is increased, the local microstructure transition and the hardness of work roll face are low during the rolling process. Improve work roll end hardness and strengthen the use of roll management, the work roll life is improved.
