FIELD: chemistry.
SUBSTANCE: invention relates to the technology of briquetting carbonaceous fuel, and can be used in metallurgy and other industries. The method of briquetting fine coke grains involves making a briquette from fine coke fractions and depositing a protective coating on the briquette, where the said briquette with a defined shape, made using various methods, is placed on charplets in a snap flask, into which molten blast-furnace or steel slag is fed through a sprue channel, cooled and a briquette is taken out, coated with a layer of slag which is porous, has high mechanical strength and heat resistance.
EFFECT: invention increases strength and heat resistance of briquetted fine coke, and also increases efficiency of using recycled materials.
