METHOD FOR CONTROLLING BLAST FURNACE OPERATION Russian patent published in 2001 - IPC

Abstract RU 2167202 C1

FIELD: ferrous metallurgy, namely, production of cast iron in blast furnace. SUBSTANCE: method comprises steps of loading worn lining of chutes of furnace casting bed with carbon content more than 50% into furnace for melting cast iron of iron-ore materials with different alkalinity of iron ore material mixture while partially changing coke with fraction size 10-25 mm used for mixing with low-alkalinity material. EFFECT: enhanced ecology of blast furnace production. 3 cl, 1 ex
