摘要/Abstract

摘要： 根据熔渣体积与温度的线性关系，结合不同组分与温度下密度的实验测量值，建立了简单而准确的SiO₂-Al₂O₃-CaO-MgO四元系熔渣密度计算模型，利用该密度模型绘制了Al₂O₃质量分数分别为10%, 20%, 30%, 40%，温度为1773和1873 K的条件下的等密度图. 结果表明，模型计算的渣系密度值与文献报道的实验结果一致，相对误差为1.08%，绝对误差为0.041 g/cm³. 随SiO₂含量增加，密度显著减小，温度对密度的影响较小.

Abstract: A simple and accurate density model for SiO₂-Al₂O₃-CaO-MgO molten slags was established in this work, based on the linear relationship between molar volume and temperature. The model was calibrated by open published density measurements. Using current model, the iso-density lines for SiO₂-Al₂O₃-CaO-MgO with 10%, 20%, 30% and 40% mass fraction of Al₂O₃ at 1773 K and 1873 K were plotted. The results showed that the calculated density values agree very well with measured values, with remarkable relative error of 1.08%, and absolute error (RMSE) of 0.041 g/cm³. It reveals that the density of the slags decreases obviously with increasing SiO₂ content, whereas the effect of temperature on density is smaller.

Key words: SiO2-Al2O3-CaO-MgO slag system, density model, blast furnace slag, refining slag
