Substitution of Coke and Energy Saving in Blast Furnaces. Part 3. Study of Influence on the Processes of Individual Blast Parameters
The system of discrete material and thermal balances in the radial annular cross-sections for 12 vertical and 10 radial ring zones is used to describe the heat and mass transfer processes of iron ore reduction and melting in blast furnace with respect to the various degrees of blast parameters.
The model makes it possible to determine the relationships that exist between processes which take place in the furnace and which affect the character of the smelting regimes and the final results. The study is performed for a wide range of blast temperatures, different oxygen contents in the blast, by variation in the flow rates of natural gas, coke-oven gas, pulverized coal and different distributions of the charge materials over the furnace radius. New scientific results are obtained along with conclusions that can be put to practical use.
