根据炉渣结构的离子理论,假设熔渣的黏性活化能与熔渣质点间距离(键长)成反比,考虑了熔渣中各种离子质点相对纯SiO2的移动能力,基于Arrhenius公式推导了一个由熔渣中质点浓度预报硅酸盐熔渣黏度的理论模型。并根据离子理论按炉渣成分分段计算各质点浓度,通过SiO2-Al2O3-CaO-MgO四元系炉渣黏度试验数据确定了模型中的各个参数,并且通过其他文献的试验数据验证了这些参数适用于相应的二元及三元渣系。预报结果与国内外文献中大量的试验数据(二、三、四元系)基本相符,与试验结果的平均相对误差在20%左右,与其他模型相比准确度较高。
According to the ion theory of the slag structure, assuming that the viscous activation energy of the slag is inversely proportional to the distance between the slag particles (bond length), the mobility of the various pure SiO2 ions in the slag is considered. Based on the Arrhenius formula, Predicting the viscosity of silicate slag from the concentration of particle in slag. Based on the ion theory, the concentration of each particle was calculated by the fractional composition of slag. The parameters of the model were determined by the viscosity test data of SiO2-Al2O3-CaO-MgO quaternary system slag. The experimental data of other literatures proved that these parameters are suitable for The corresponding binary and ternary slag system. The prediction results are in good agreement with a large amount of experimental data (two, three, four yuan series) in literature both at home and abroad, with an average relative error of about 20% compared with the experimental results, which is more accurate than other models.
