An examination is made of the main problems and methods of optimizing the gasdynamic regime of blast furnaces. The gasdynamic regime depends mainly on the distribution of materials in the top of the furnace. The interactive system CHARGING – which models charging by a bell-less charging apparatus – is used to determine the configuration of the layers of charge materials and calculate the distribution of burden coke along the radius of the top. Improvements were made to the charging regimes on blast furnaces Nos. 3 and 4 at the Azovstal Metallurgical Combine. The blast parameters of the furnaces at the combine were optimized by using the interactive BLAST system. This system used the parameters specified for the blast to calculate generalizing characteristics of the blast regime and correct the blast parameters as needed in order to keep the generalizing characteristics at their optimum levels.
