Abstract:
The blast furnace industry is one of two productions under the base methods of manufacture of steel “the blast furnace - the converter”. Now in the world it is fabricated about 950 million tons of pig-iron per annum, for its production it is spent about 400 million tons of unprofitable and expensive coke per year. Specific coke consumption in the blast furnace smelting and productivity of the blast furnace are substantially defined by processes of heat and mass transfer. Therefore use of mathematical models in study blast furnace smelting, at system engineering monitoring and control of a blast-furnace smelting operation is great importance. The role of mathematical models will increase at a shortage of the information on the phenomena happening in the furnace such as temperatures of material and gas, pressure and composition of gas, a degree of reduction of iron in volume of the furnace. In this paper the modern conceptions about heat and mass transfer in the blast furnaces are given. The two-dimensional mathematical model of heat interchange founded on an original mathematical model of the gas dynamics is presented. In the paper the solution of some problems of the blast furnace smelting having theoretical and practical significance are considered.
