铁浴式熔融还原型熔体的性质

Study on the Melt Properties of Smelting Reduction Process with Iron Bath

研究了铁浴式熔融还原型熔体的组成与性质的关系；测试了熔体对耐火材料的浸润性；分析了熔体中ＦｅＯ浓度、熔体温度、耐火材料的组成及结构、耐火材料中石墨碳含量等对熔体与耐火材料间浸润性的影响；同时测试了熔体组成与流动性的关系，熔体中ＦｅＯ浓度、熔渣碱度对熔体的熔化温度的影响；测定和分析了熔体组成与粘度变化的关系。结果表明，熔体中ＦｅＯ浓度是影响熔体性质的最关键因素。ＦｅＯ浓度提高，熔体对耐火材料的润湿能力提高，熔体的熔化温度降低，而粘度变化与ＦｅＯ的含量有关。

In this paper the relation between melt composition and its properties has been investigated. Permeability of melts to refractories is tested. Influence of melt composition, temperature,refractory quality, carbon content in qraphite and others on permeability of melt to refractory is also analysed.Meanwhile,fusing temperature and viscosity are tested.It is shown that the key factor effecting the properties of melts is ferric oxide,The higher the content of ferric oxide is in the melts, the strenger the permeability of melts to refractories is and the lower the fusing temperature of melts is.The change of melt viscosity is also related to ferric oxide content.
