Abstract:
Laboratory researchers and mathematical modeling of the physicochemical and thermophysical processes, carried out in Institute of Metallurgy, have for an object establishment of the formation mechanism of metallurgical properties of agglomerate and pellets at oxidizing roasting and an estimation of influence of metallurgical properties (reducibility, durability, softening and melting temperatures) on processes heat and mass exchange at the reduction in the blast furnace. At the same time, the principal reserve of decrease of the coke consumption and improvement of technical and economic indicators of blast furnace smelting is an improvement of the quality of iron ore raw materials. A new method for the estimation of the influence of the iron ore materials metallurgical properties on the efficiency of blast furnace smelting is developed. It consists of the following stages: the laboratory tests with the definition of the iron ore materials metallurgical properties; the analytical study of the influence of these characteristics on the efficiency of blast furnace smelting using mathematical models; the experimental industrial and industrial tests. Examples of an assessment of metallurgical properties of agglomerate and pellets from a titanomagnetite concentrate and results of calculation of indices of blast furnace smelting are given.
