摘要

根据TWIP钢裂纹敏感性强和高洁净度要求

通过分析和计算

采用65CaF

-25Al

-10CaO渣

AOD精炼的2根0.6 m直径7.3 t电极(/%:0.03C

2.75Si

25.13Mn

0.019P

0.002S

2.50Al)

重熔14 t TWIP钢电渣锭(/%:0.03C

2.88Si

24.71Mn

0.021P

0.007S

2.98Al)。检验结果表明

重熔后钢中夹杂物乎均尺寸减少36.4%

夹杂物总量降低46.7%;电渣时应采用氩气保护以减少钢中Al、Mn的烧损。

Abstract

Based on strong crack sensitivity and requiring high cleanliness of TWIP steel

with analysis and calculation the 14 t TWIP steel ESR ingot (/%: 0. 03C

2. 88Si

24. 71 Mn

0. 021P

0. 007S

2. 98Al) has been remelted with 65CaF

-25Al

-10CaO slag by AOD refined two 0. 6 m diameter 7. 3 t electrode (/%: 0. 03C

2. 75Si

25. 13Mn

0. 019P

0. 002S

2. 50Al). Examination results show that the inclusions average size in remelted steel reduces by 36.4% and the total inclusions amount decreases by 46. 7 %. Argon atmosphere should be used to reduce the loss of Al and Mn in ESR process.
