Abstract

The analysis of coke-saving modes of blast furnace which was performed basing on the developed in the Institute of Ferrous Metallurgy NAS of Ukraine mathematical model, showed the possibility of a step-by-step implementation of alternative modes: the charge of lump coal into the furnace with improved properties of raw materials - the use of pulverized fuel - injection of coal gasification products. This scheme will reduce coke consumption to the level of 200 kg / t of pig iron.
