【摘要】 用Ｏ_２、Ｎ_２、Ａｒ气体对铁水进行吹炼处理，分析了吹炼处理的热力学与动力学原理，研究了吹炼处理的气体组成、吹气强度、吹气方式以及铁水温度对铁水成分与铸件质量的影响，并在３ｔ铁水包中对高炉铁水直接进行吹炼处理．研究结果表明，高炉铁水直接吹炼处理后可用于生产牌号铸件，明显提高铸件品质．更多还原

【Abstract】 The treating process of blowing O₂、 N₂ Ar into molten cast iron and the dynamics and thermodynamics of the blowing process are studied. The effects of gas composite, blowing intensity, blowing form and molten iron temperature on molten iron composition and casting quality are analysed. And molten pig iron of the blast furnace is blown in 3t ladle. The results show that the molten pig iron after direct blowing treatment can be used to make quality costing.更多还原
