| 摘 要： | 运用热力学理论和通过工业试验对冶炼Ｍ２钢进行了脱磷研究。研究表明，用ＣａＯ渣系氧化脱磷磷时，〖Ｗ〗、〖Ｍｏ〗不会氧化，但〖Ｃｒ〗、〖Ｖ〗氧化损失严重；用ＢａＯ渣系氧化脱磷时，〖Ｐ〗先于〖Ｃｒ〗〖Ｖ〗氧化；用Ｃａ、ＣａＣ２、ＣａＳｉ可实现还原脱磷；还原法脱磷用于冶炼Ｍ２钢比冶炼不风更有效。

| Abstract: | The research on dephosphorization during smelting M2 steel is carried out by thermodynamics and industrial trial,the result of which shows that[W]and[Mo]are not oxidized while [Cr]and[V]are oxidized and lost seriously when using Cao slag for oxidizing-dephosphorizing.[P]is oxidized preferentially to [Cr]and[V]when using BaO slag for oxidizing-dephosphorizing.So reducing-dephosphorizing is available when using Ca,CaC 2 or CaSi.Reducing dephosphorizing for smelting M2 steel is more effective than that for smelting stainless steel. |
