摘要

研究了100 t EBT DC电弧炉-100 t LF/VD-300 mm×340 mm连铸坯生产GCr15轴承钢、齿轮钢时

电弧炉终点[C]、精炼渣、吹氩工艺、Als、保护浇铸、钢水温度及耐火材料等工艺参数对钢中Ds出现几率的影响。实践表明

采用较高的终点[C](≥0.10%)、精炼渣碱度2.5～3.5、真空后弱搅拌时间≥15 min、Als控制在0.011%～0.020%、良好的保护浇铸以及选用优质耐火材料等措施

可降低钢中大颗粒点状夹杂的出现几率。

Abstract

The effect of process parameters such as arc furnace end [C]

refining slag

argon blowing

Als

shielding casting

liquid steel temperature and refractory material etc on occurred probability of Ds in CCr15 bearing steel and gear steel produced by 100t EBT DC EAF- 100 t LF/VD-300 mm × 340 mm billet process has been studied. The practice showed that with using higher end[C] (≥0. 10%C)

refining slag basicity 2.5~3.5

≥15 min soft argon stirring after vacuum treatment

controlling Als 0.011%～0.020%

favorable shielding casting and using excellent refractory materials

it was available to decrease large size globular oxides inclusions in steel.
