摘　　要：长城特殊钢公司（３０～３５ｔ）单嘴精炼炉冶炼轴承钢试验表明，合理的脱氧工艺为：电弧炉不加铝终脱氧出钢＋单嘴炉真空碳脱氧＋硅、铝沉淀脱氧。这种工艺可使轴承钢氧含量达到１０～２０ｐｐｍ，其中≤１５ｐｐｍ的占５０％，无点状夹杂。文中分析了各种工艺因素对轴承钢氧含量的影响，并提出了合理的工艺因素。More than 100 heats experiments on bearing steel deoxidization were carried out by the(30 ～ 35)tons single-snorkel refining furnace at Changcheng Special Steel Co. The detailed results show that reasonable deoxidization process is as follow:steel tapping without final A1- killed + VCD treating + Si、A1 deoxidizating. The content of the oxygen of bearing steel treated with the above process is in the range of 10～20 ppm,less than 15 ppm constituting 50%,and the globular inclusions was not found. On the basis of the the analysises of the factors affecting the oxygen content,the reasonable deoxidization parameters were suggested.
