電渣重熔與連鑄軸承鋼中的夾雜物

Inclusions in Electroslag Remelting and Continuous Casting Bearing Steels

摘要: 研究了電渣重熔前后鋼中氧及夾雜物的變化,結果表明:用電渣重熔工藝生產軸承鋼,雖然氧含量比連鑄鋼高,但其大顆粒夾雜物數量少,尺寸較小,分布均勻,因此疲勞壽命高.

Abstract: Changes of oxygen and inclusion during electroslag remelting (ESR) of bearing steel have been investigated. Although the oxygen content in ESR steel is higher than that of continuous casting (CC) steel, the fatigue life of ESR steel is higher than the latter because of its less large size and well dispersed inclusions.
