摘要

石钢采用60t氧气顶吹转炉-LF+VD-CC流程生产高碳铬轴承钢。602炉次至2449炉次的统计数据表明

转炉冶炼时采用高拉碳操作

平均终点碳为0.15%、[P

]

0.012%、[S

]

0.034%。LF+VD精炼后

钢中平均氧含量为9.4×10

-6

Ti含量为52×10

-6

但存在钛、氧含量波动较大

需进一步改善工艺和操作。

Abstract

The high carbon bearing steel is produced by 60 t LD-LF+VD-CC flow sheet at Shijiazhuang Steel. The statistical data with 602～2449 heats showed that in LD steelmaking the average end-point carbon was 0. 15% by catch carbon practice

the average end-point [P

]

0.012% and the[S

]

0.034%. After LF+VD refining the average oxygen content in steel was9.4×10

-6

and the Ti content was 52×10

-6

but the fluctuating range of [Ti

]

and [O

]

was relatively large needs to further improve process and operation.
