摘要
研究了电渣重熔前后钢中氧及夹杂物的变化，结果表明：用电渣重熔工艺生产轴承钢，虽然氧含量比连铸钢高，但其大颗粒夹杂物数量少，尺寸较小，分布均匀，因此疲劳寿命高．
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.
