摘要
武钢鄂钢公司采用70 t Consteel EBT EAF-LF(VD)-CC工艺生产高碳铬轴承钢GCr15棒材。通过控制电弧炉终点碳≥0.25%和高碱度渣精炼,使[S]≤0.004%,T[O]0.000 8%～0.001 2%。检验结果表明,钢中非金属夹杂物A、B类夹杂物≤1.20级,C类夹杂物为0,D类夹杂物≤0.5级。
The bar products of high C chromium bearing steel GCr15 are produced by 70 t Consteel EBT EAF - LF （VD） -CC process at Egang Co, Wuhan Iron and Steel. The results showed that with controlling EAF end carbon ≥ 0. 25%, using high basicity slag refining, so that [ S] ≤0. 004%, T[ 0] 0.000 8% - 0.001 2%, the rating of A and B series inclusions in steel was respectively ≤ 1.20, of C series inclusions was 0 and of D series inclusions was ≤0. 5.
