摘要 研究了加入不同比例铁矿废石或粉煤灰的高炉矿渣成分的变化,及对矿渣作为制备矿渣棉原料的影响,并对其影响机制进行了分析。结果表明,随着铁矿废石或粉煤灰配加比例的增加,矿渣中SiO2和Al2O3总含量逐渐升高,CaO、MgO、Fe2O3、FeO、K2O和Na2O的总含量降低,矿渣酸度系数Mk和粘度系数Mη值升高,氢离子指数pH值降低,熔渣粘度增加,但是在高温区粘度变化较小;由此可以预测,上述成分的改性矿渣更适合制备矿渣棉纤维。 The composition change of molten slag, adding different proportions of waste iron ore or fly ash, was studied, and the impact mechanism of molten slag as a raw material preparation slag wool was analyzed. The results show that, with the increase of waste iron ore or fly ash proportion, the total content of SiOz and Al2O3 in the molten slag increases gradually , the content of CaO, MgO, Fe2 03, FeO, K2 O and Na2O decreases, the acidity coefficient Mk and viscosity coefficient Mη value of molten slag increase, hydrogen ion index pH decreases, slag viscosity increases, but viscosity in the high temperature zone changes a little, so it is conductive to produce slag wool fiber.
