摘要
介绍了轧辊材料中残余奥氏体的特点与影响因素。少量的残余奥氏体有利于提高轧辊的整体强度和韧性。回火和深冷处理工艺可以有效地控制残余奥氏体量。
The characteristics and influence factors of residual austenite in the roller have been described. A small amount of residual austenite is good for increasing the overall strength and toughness of roller. The tempering process and the sub-zero treatment can control the amount of residual austenite effectively.
