摘　　要：在真空感应炉中冶炼超洁净钢种,硫含量的控制是一个难点。本文设计了四种不同的冶炼方案,研究了脱硫渣成分配比、脱硫渣量、精炼参数、钢液中的碳含量、脱硫渣的加入时间等因素对钢液中硫含量的影响。结果表明,将1000 g含Ca O、Ca F2各50%的脱硫渣随炉加入坩埚内,选择合适的精炼参数,在允许的范围内提高钢液中的碳含量,钢液的脱硫率可达80%以上。It is difficult to control the sulfur content for smelting super clean steels by vacuum induction furnace. In this paper, we design four smelting schemes to discuss the effect of desulfurization slag composition, desulfurization slag weight, refining parameters, the carbon content in molten steel and the slag adding time on the sulfur content in molten steel. When adding 1000 g desulfurization slag mixed with 50% CaO and 50% CaF2 to raw materials, the desulfurization ratio will reach to 80% on the basis of appropriate refining parameters. In appropriate conditions, we should increase carbon content in molten steel.
