The most important problem at the blast furnace process developing is the great coke consumption decreasing at the minimization of the general energy costs. One of the most effective ways of iron-making technical progress is the iron ore materials and coke physicochemical properties improvement which allows to increase the iron productivity and decrease the specific coke rate without construction of new blast furnaces and concentrating mills. Some of the quality indicators of iron ore raw materials and coke and their influence on the main parameters of a blast furnace smelting are considered in the paper.

The technique of defining the minimum coke consumption in blast furnace smelting allows for the calculation of the reserve of coke economy on the basis of thermodynamic principles. In this reserve the constitutive role belongs to the reducibility of the iron ore materials (the agglomerate and pellets). In the present paper, the questions of the reduction kinetics of the iron ore materials and diffusion processes at reduction of iron from its oxides are considered. It is shown that the reducibility of the iron ore materials is the basic reserve of economy the scarce and expensive coke in the blast furnace smelting.

The article presents the results of the analysis of production data on the operation of the blast furnace No. 1 of Ural Steel JSC for the period from 2013 to 2018. During this period, the Mikhailovsky GOK pellets with different basicities were used. It has been established, that the effectiveness of the use of pellets of different basicities is determined by their behavior in a blast furnace and depends on the proportion of pellets in the iron ore part of the charge. The gas-dynamic conditions of melting deteriorate with an increase in the proportion of pellets in the charge, which is accompanied by an increase in the specific pressure drop and forces the blast rate, to be adjusted. It is necessary to work on 40-45% of fluxed pellets and 20-25% acid pellets in a charge at a blast rate of 2000-2100 m3/min, to minimize coke rate and increase rate of work of blast furnace No. 1 of Ural Steel JSC. An increase in pellet consumption is possible while maintaining the efficiency of blast-furnace smelting only if their high-temperature properties are improved, as a result of optimization of basicity and increase in MgO content, which affects the structure and properties of the silicate binder.

Furnace Smelting

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.
