摘要

为了改善酒钢CSP流程生产的低碳铝镇静钢中的非金属夹杂物问题

对其炼钢和连铸等各个阶段取样

通过金相组织分析、电子探针及扫描电镜观察对钢中氧夹杂物进行了研究。结果表明

现行工艺铸坯中含T[O

]

30×10

-6

以上

通过采用转炉冶炼N

/Ar切换工艺、LF软吹≥6 min、钢包浇注余量2%～4%等工艺措施后

使2μm夹杂物≥66%

球形夹杂物≥94%

夹杂物类型以钙铝酸盐加一定量CaS为主。工艺优化后

各项指标满足DQ级深冲钢的要求。

Abstract

For improving the problem of non-metallic inclusions in low carbon aluminum killed steel produced by CSP process at Jiuquan steel Co

with sampling at each phase of steelmaking and continuous casting

the study of inclusions in steel is carried out by metallographic analysis

electron probe and scanning electron microscopy. The results show that under the current process conditions

the casting slab T[0

]

is more than 30 x 10

-6

by BOF blowing N

/Ar exchange process

LF soft blowing 36 min and lable heel 2% ~4%

the 2μm inclusions ≥66% and spherical inclusions ≥94%

and the type of inclusions is mainly calcium aluminate plus a certain amount of CaS. After the process optimization

all indexes meet the requirements of DQ deep drawing steel production.
