FIELD: metallurgy.
SUBSTANCE: briquetting method of semi-coke, mainly lignite, includes stages of preparation of initial components, blending, compressing, drying and impregnation provides grinding of initial components on stage of preparation up to granulometric compound 0-7 mm, and addition of slaked lime with water-calcareous ratio 3/1-5/1 with content CaO from 5 up to 15%, and after blending of components, compressing and drying, and also impregnation of briquettes by solution of liquid glass.
EFFECT: hardening of briquettes, leading to ability of multiple implementation of loading processes with briquettes, allowing water-resisting property.
