Method for the blast furnace loading

摘要

A method for the blast furnace loading includes supplying ore component to the furnace, which is divided into two portions with the size of 30-70% of its total weight in the skip and placing between these portions of the nut coke with a particle size of 8- and metallurgical coke. Some nut coke with a particle size of 8-15 (20) mm is loaded in such quantity that this nut is enough for the fully direct iron reduction up to 30%, and some nut coke of the larger fraction [16 (21) - 40 mm]. Part of metallurgical coke is loaded in the quantity of not more than 25% of the total weight of coke in the supply, at that all nut coke [fraction of 8-15 (20) mm and fraction of 16 (21) - 40 mm] and of part of the metallurgical coke are charged in the mixture into one skip during each loading.
