The analysis of the general and zonal thermal balances of blast-furnace smelting is performed. In modern blast furnace conditions, the specific consumption of coke is determined by the development of heat exchange processes occurring in the lower zone of the furnace. At the same time, the heat losses found using the heat balance of the lower zone of the furnace sufficiently reflect such technological indicators as specific coke consumption and silicon content in cast iron. It is shown that the existing methods of analytical calculation of the heat losses that occur during the smelting of pig iron in blast furnaces do not reflect the actual melting process. It is established that the analysis of the heat balance of the lower stage of heat exchange makes it possible to determine the heat losses in this zone of the furnace and to estimate the cor- rection factors when the conditions for blast furnace smelting change. The control of heat losses is necessary for estima- tion of condition of a refractory masonry of BF, rational gas distribution, and also for correction of the expense of coke.
