Iron Ore Materials and Coke Quality Characteristics and Quantitative Indicators of Blast Furnace Smelting

One of the most effective ways of the technical progress in the blast furnace manufacture is improvement of physical and chemical characteristics the iron ore materials and coke that allows to increase the smelting of pig-iron and to reduce the coke specific consumption without building of new blast furnaces and concentrating plants. The coke consumption in blast furnace smelting make about 40 % of costs for pig-iron production. Therefore essential reduction of the coke consumption at the minimization of the general power costs should be considered as the important problem at the enhancement the blast furnace smelting technology. In the paper following approach to the decision of practical problems of the blast furnace is considered: the laboratory researches at the experimental installations and definition the qualitative characteristics the iron ore raw materials and coke; analytical research by means of the mathematical models; pilot and industrial tests.
