Abstract

The expansion of coal injection under shortage conditions of necessary coal grades and dynamic change in prices needs the development of a wide range of coke replacement production technologies for implementation of the most effective option at each stage on the basis of combination with coke gas, stone coal, coal gasification products, etc. Blast-furnace smelting with hot reducing gas injection - low-grade coal gasification products – needs to work out for fundamental solution of coke saving problem.
