4CrMo超深淬硬层冷轧工作辊组织性能分析

Analysis on Structural Performance of 4CrMo Cold Rolling Worke Roll

通过对进口4CrMo超深淬硬层冷轧工作辊进行检验和上机使用跟踪,弄清了4CrMo超深淬硬层冷轧工作辊的材质成分、金相组织、残余奥氏体含量、硬度、硬度均匀性、强度和冲击韧性等各项指标。由于金相组织细小,碳化物呈均匀、弥散分布,其硬度均匀性较好,强韧性和耐磨性较高,表明4CrMo超深淬硬层冷轧工作辊值得推广和研制应用。

A comprehensive description is given in this paper of the improvements on introduced 4 CrMo cold rolling work roll with a super deep hardening layer.Such rolls are characterized by fine microstructure,uniform and dispersive distribution of carbide,satisfacfory uniform hardness、toughness、resistance to abrasion,and so deserve publicity.
