FIELD: ferrous metallurgy; briquetting and making use of iron-containing waste.
SUBSTANCE: briquette includes iron-containing waste of metallurgical process at the following ratio, mass-%: blast-furnace dust, 1-40; dust-like dolomite, 5-30; cement used as binder, 1-5 and dust of gas cleaning of electric steel making process, 40-80. Invention ensures increase of good-to-bad yield by iron by 0.1%.
EFFECT: enhanced mechanical strength of briquettes; utilization of steel making process waste.
