摘　　要：为进一步控制GCr15轴承钢液析碳化物超标,采用提高连铸方坯加热温度、延长高温保温时间和喷涂防粘钢涂料在钢坯表面等工艺,使GCr15轴承钢的液析碳化物得到了控制。新工艺下,GCr15液析碳化物≤2.0级,合格率达100%,取得了明显效果。In order to control the liquation carbonide of GCrl5 bearing steel exceeding the standard, through raising the heating temperature of continuous casting billet, prolon- ging the holding time at high temperature and spraying non-stick coating for steel in bil- let surface, the liquation carbonide of GCrl5 bearing steel is under control. The grade of the liquation carbonide of GCr15 bearing steel is not more than 2.0 grade under the new technology process, and the percent of pass is up to 100% .
