用非煤系惰性物替代标准无烟煤的研究

A Study on Using Non-coal Inertinite to Replace Standard Anthracite

通过对多种非煤系惰性物的粒度、煤/惰比及比表面积等因素对炼焦用煤粘结指数影响的研究、对比,找出了与专用标准无烟煤所测得的粘结指数有良好相关性的非煤系惰性物。

Through the study and comparison of the effects of the factors such as thegrain size, ratio of coal to inertinite, specific area of considerable variety of non-coal inertinite on the caking index of cokemaking coal, the non-coal inertinite correlating well with the caking index measured from a special standard anthracite are found.
