摘要

天津钢管公司采用150 t EAF-150 t LF(VD)-CC工艺生产30CrMo

37Mn等气瓶钢Φ210~310 mm圆管坯。生产统计数据表明

在LF精炼时用Si≥50%

Ca≥12%

Ba≥13%合金替代全用Al脱氧

使[Al

]

从0.026%降至0.006%

钢中氧含量为25×10

-6

提高了钢的清洁度

减少了轧制过程中钢材的裂纹废品。

Abstract

The Φ210~310 mm round tube billet of gas bottle steels such as steel and steel 30CrMo and 37Mn are produced by 150 t EAF- 150 t LF(VD)- CC process at Tianjin Pipe Co.The production statistic data showed that during LF refining using ≥50Si

≥12Ca

≥13Ba alloy to replace total aluminium deoxidization

the [Al

]

decreased to 0.006% from 0.026%

the oxygen content in steel was 25×10

-6

with the result that the cleanliness of steel increased and the clack rejection rate decreased obviously.
