摘要/Abstract

摘要： 采用FactSage模拟软件和修正后的Einstein?Roscoe公式计算了无氟型CaO?SiO2?FeO?B2O3?MnO预熔脱磷渣的熔化温度和粘度，考察了碱度和各成分配比对脱磷渣熔化温度和粘度的影响，得到合理的脱磷渣成分配比及控制区间和适宜的熔池温度，采用正交法进行了实验验证，通过直观分析、方差分析和主效应分析优选出最佳配比. 结果表明，该渣系粘度随碱度、FeO含量和助熔剂含量提高而降低，1400℃时最佳配比为碱度R?4.0, B2O3含量9wt%, MnO含量10wt%, FeO含量45wt%. 计算的熔化温度为1195.51℃，粘度为0.207 Pa×s，实验所测熔化温度为1192.21℃，粘度为0.199 Pa×s，计算值与实测值相近，表明正交法优选方案可靠.
