摘　　要：通过利用喷吹法和四辊离心法制备矿渣棉,研究在不同制备方法条件下,矿渣棉其化学稳定性、表观特征、含水率及渣球含量与酸度系数之间的关系。结果表明：在满足成纤要求的前提下,高炉渣酸度系数应控制在1.2~1.4;利用喷吹工艺制备的矿渣棉直径较细,含水率较低,成纤率较低,渣球含量较高纤维质量较差;相对于喷吹工艺,离心法制备的矿渣棉直径相对较粗,含水率大,渣球含量较少,成纤率较高,纤维质量较好。The slag cotton was prepared by spray blowing and four centrifugal centrifugal preparation. Under different methods,the relationship between slag wool,chemical stability,surface characteristic,water content and slag content and the acidity coefficient is studied. The results showed that under the premise of meet the requirements of fiber forming,the acidity coefficient of blast furnace slag should be controlled at 1. 2 ~ 1. 4,the diameter of slag cotton of blowing process is smaller,the water content is low,but the content of slag ball is high,the diameter of slag cotton of centrifugation is relatively coarse,the water content is high,the content of slag ball is low.
