    摘要
  • 摘要: 系統地研究了國內某鋼廠生產的3 9Mn2V石油套管鋼鈣處理前后的總氧含量變化及夾雜物類型,從熱力學上分析了鋼中氧化鋁和硫化錳的變性機理.研究結果表明現有工藝條件下喂入的硅鈣量可以將Al2O3完全變性為煉鋼溫度下呈液態的12CaO· 7Al2O3和3CaO· Al2O3夾雜物,但不能將MnS完全變性為CaS.

     

    Abstract: A systematic investigation was carried on the variations of total oxygen content and inclusion types in 39Mn2V steel before and after calcium treatment.The modification mechanism of Al2O3 and MnS was analyzed by thermodynamics.The results show that Al2O3 can be wholly modified into 12CaO·7Al2O3 and 3CaO·Al2O3 inclusions which are liquid at steelmaking temperature,while MnS just can be modified partially into CaS under the present amount of Ca-Si wire fed.
