Beschreibung
Zusammenfassung:	A method for the preparation of metallurgical charge for the blast furnace process involves dosage of original charge components which contain iron ore component, fuel and flux binding agent, mixing thereof, moistening (water), granulation, charging granules layer on the band conveyer machine, drying granules layer and thermal strengthening thereof. Besides, as flux binding agent the carbonate lime is used, for mixing charge components 80-20 % ofnecessary solid fuel (coke) is supplied, the rest of solid fuel is rolled on the surface of preliminarily obtained granules, rolling is performed up to obtaining granules of the size of 5-15 mm, at that the iron ore component contains 60-100 % of ferric concentrate and 0-40 % of iron ore, and size of particles is of 0-3 mm.
