Essay

Object - distributing of speeds and pressure of gases in the layer of blast-furnace charge; the purpose - development of effective measures on the improvement of technical and economic indexes of work of blast-furnaces in modern conditions with short purchase period, which don't need the large capital investments, due to the management by distributing of raw materials and gases on the basis of theoretical positions of geometry of grained layer and gas dynamic of opposite stream reactors; methods - the mathematical and physical design, planning of experiments, experiments in laboratory and on operating blast-furnaces, balance methods of analysis of indexes of blast-furnaces; novelty - the integral theory of void volume of grained material is developed firstly, on the basis of the mathematical model of distributing of static pressure of gas on the height of blast-furnace decreasing of hydrodynamic resistance of area of softening influence of charge at forming of the developed axial stream of gases is proved, the methods of determination of overfall of pressure of gas in a grained layer, estimation of influencing of unevenness of distributing of blast-furnace charge on its gas-permeability are improved; results - the methods of selection of composition of multicomponent blast-furnace charge, the charging of blast-furnace are developed, new modification of charging device with the axial technological opening in a large cone and mobile flags in intercone space, conditions of forming of continuous axial column of coke in a blast-furnace are certain; area of use - charging of blast-furnaces.
