摘　　要：为使高炉渣酸度系数满足生产矿棉的要求,分别采用石英砂和粉煤灰在实验室进行了调节矿渣酸度系数的试验,对比物料熔融温度、时间和熔融料的流动性,用石英砂和粉煤灰都可以调节熔融料的酸度系数,而要达到相同的酸度系数,使用石英砂,添加量更少,物料熔融温度更低,耗时更短,流动性更好,能耗更低。In order to make the acidity coefficient of blast furnace slag to meet the needs, of producing mineral cotton, some experiments were done to modulate the acidity coefficient of slag by adding quartz sand and fine coal ash respectively in laboratory. By comparing the fusing temperature, time consuming, and the fluidity, we got the results that both of the two auxiliary materials can be used, and adding less quartz sand than free coal ash can achieve less time and energy consuming and better fluidity.
