【摘要】：采用自主设计搭建的实验平台,利用高速气流喷吹的方法,进行高炉热熔渣成纤试验,探讨熔渣成纤机理,分析影响纤维直径及性能的因素。结果表明:采用喷吹法制备矿渣纤维,熔渣经过液膜形成、凸起形成和凸起拉丝三个过程形成纤维;随气量压力的增大,纤维直径越细;调质熔渣酸度系数为1.1~1.4,温度在1 350~1 500℃制得纤维性能较好,此研究为工业扩大化生产提供理论依据。
[Abstract]:By using the experimental platform designed by ourselves and the method of high speed airflow injection, the experiment of hot melt slag fiber formation in blast furnace was carried out, and the mechanism of slag forming was discussed. The factors affecting fiber diameter and properties are analyzed. The results show that the slag fiber is prepared by injection, the slag is formed by liquid film, bulge is formed and protruding wire is drawn, and the diameter of the fiber is finer with the increase of gas pressure. The acidity coefficient of quenched and tempered slag is 1. 1 / 1. 4 and the temperature is 1 350 ~ 1 500 鈩，
