研究了在EAFEBTLFVDCC冶炼工艺下影响轴承钢GCr15洁净度的N、Ti、Ca、S、O等元素的变化规律，以及对GCr15质量的影响。结果表明： EBT出钢和LF精炼期的增N量可以通过VD真空脱气和钢包软吹氩去除，而Ti的来源主要在于合金和耐火材料的带入；EBT出钢过程中加入活性石灰和Ca处理都易导致钢中Ca含量的增加；高碱度精炼渣有利于钢水脱硫，但不利于改善钢中夹杂物的性质和形态；GCr15钢中夹杂物主要是呈菱形的氮化钛和硅铝镁氧化物夹杂。

The change of N,Ti,Ca,S content in steel GCr15 during EAFEBTLFVDCC process and effect on the product quality were studied. The results showed that the nitrogcn pickup during EBT tapping and LF refining could be eliminated by vacuum treatment and soft Ar blowing in VD process and Ti comes from alloys and refractory; EBT tapping with active lime addition and Cawire feeding could result in the increment of Ca content; high basicity refining slag is benefit to desulfurization, but without modification of inclusions; the major inclusions of GCr15 are rhombic TiN and oxides of Si,Al,Mg.
