采用真空感应和真空自耗双真空（ＶＩＭ＋ ＶＡＲ）冶炼工艺生产的ＨＧＣｒ１５ 轴承钢，其中氧含量仅为（５ ～７） ×１０－ ６ 。电渣钢ＺＧＣｒ１５ 的氧化物夹杂含量是双真空ＨＧＣｒ１５ 轴承钢的４－２ 倍。经真空热处理后轴承零件（ＨＧＣｒ１５） 表面可以获得压应力。双真空ＨＧＣｒ１５ 的接触疲劳寿命Ｌ１０是电渣钢的１－４９ 倍，断裂韧度ＫＩＣ提高１９％ 。
The HGCr15 bearing steel produced by vacuum induction and vacuum consumable double vacuum (VIM + VAR) smelting process has an oxygen content of only (5 ~ 7) × 10 -6. Electrochemical slag ZGCr15 oxide inclusions content is double vacuum HGCr15 bearing steel 4-2 times. After vacuum heat treatment bearing parts (HGCr15) surface can get compressive stress. The contact vacuum life H10 of double vacuum HGCr15 is 1-49 times that of electroslag, and the fracture toughness KIC increases by 19%.
