Cleanliness of GCr15 Bearing Steel Produced by Hot Metal Pretreatment→120 t LD→LF→RH→CC Process
摘要
Abstract
The oxygen,nitrogen and residual elements contents,non-metallic inclusions rating and inclusions morphology and compositions of 7 furnaces GCr15 bearing steel produced by technological process of hot metal pretreatment→120 t LD→LF→RH→CC were analyzed.The results indicate that the cleanliness of the steel was rather high,and especially the nitrogen and residual elements contents were reduced obviously,comparing with GCr15 bearing steel produced by electric furnace.The inclusions were mainly calcium aluminate,alumina,and also a small amount of sulfide and nitride,and the inclusions were always existed as complex inclusions.关键词
