| 摘 要： | 系统地研究了国内某钢厂生产的3 9Mn2V石油套管钢钙处理前后的总氧含量变化及夹杂物类型,从热力学上分析了钢中氧化铝和硫化锰的变性机理.研究结果表明现有工艺条件下喂入的硅钙量可以将Al2O3完全变性为炼钢温度下呈液态的12CaO· 7Al2O3和3CaO· Al2O3夹杂物,但不能将MnS完全变性为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. |
| Keywords: | calcium treatment sulfide alumina mechanism inclusion modified |
