| 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65CaF2-25Al2O3-10CaO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 65CaF2-25Al2O3-10CaO 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. |
