Methodical Basis of Investigation of Influence of the Iron Ore Materials and Coke Metallurgical Characteristics on the Blast Furnace Smelting Efficiency

Abstract:

A new method of the estimation of influence of the iron ore materials and coke metallurgical properties on the efficiency of blast furnace smelting is developed. It consists in the following stages: the laboratory tests with the definition of the iron ore materials and coke metallurgical properties; the analytical study of the influence of these characteristics on the efficiency of blast furnace smelting using by mathematical models; the experimental industrial and industrial tests. The developed methodological basis allows to obtain improved criteria for evaluating the metallurgical characteristics of the raw materials and to explain the mechanism of their effect on the reaction of the direct and indirect recovery in the blast furnace. Therefore it allows to formulate recommendations to improve the blast furnace smelting technology.
