BLAST FURNACE CHARGING METHOD Russian patent published in 1997 - IPC

Abstract RU 2095420 C1

FIELD: metallurgy, pig iron production. SUBSTANCE: method of charging blast furnace comprises steps of mixing and charging iron ore material with fraction size no less than 5 mm and coke at volume ratio no more than 0.5; mixing above mentioned ingredients in intermediate hopper of charging apparatus by charging coke into it and supplying iron ore material onto charged coke. Such order of mixing ingredients allows to maintain rational distribution of gas flow provided by separate feed along section of furnace. EFFECT: enhanced efficiency of method due to high technical and economical characteristics of furnace.
