摘　　要：研究了不同氧含量（（５～４０）×１０－６）的自耗电极及重熔渣系对轴承钢氧含量、夹杂物和疲劳性能的影响，结果表明：①无论用高氧含量（＞３０×１０－６）自耗电极还是低氧含量（＜１０×１０－６）自耗电极重熔，电渣钢中氧含量都保持在（１５～３０）×１０－６；②影响电渣钢中氧含量的决定因素是渣中的ａＦｅＯ值，自耗电极中的原始氧含量影响较小；③电渣重熔过程中，自耗电极中原始夹杂可基本去除，重熔钢中的夹杂主要是金属熔池冷却结晶过程中新生成的。Theeffects of ESR electrode oxygen content((5～40)×10-6) and remelting slag system on oxygen content,nonmetallic inclusions and fatigue property of remelted steel have been investigatedThe results obtained could be summarized as follows:①After ESR process,in spite of different oxygen level of the electrodes used(>30×10-6)or (<10×10-6),the oxygen content in ESR steel is (15～30)×10-6②The amount of aFeO　in the slag is the main influencing factor on oxygen content in the steel③The original inclusions in the electrode are eliminated during ESR and the inclusion in ESR steel are regenerated during the cooling and crystallization of the form of Al2O3 when the Al content of the molten steel is higher
