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。

Abstract

The bar products of high C chromium bearing steel CCr15 are produced by 70 t Consteel EBT EAF-LF (VD)-CC process at Egang Co

Wuhan lron and Steel.The results showed that with controlling EAF end carbon ≥ 0.25%

using high basicity slag refining

so that[S]≤0.004%

T[O]0.0008%～0.0012%

the rating of A and B series inclusions in steel was respectively ≤1.20

of C series inclusions wasO and of D series inclusions was ≤0.5.
