Popis:	The goal is to improve the operation of a group of blast furnaces by redistribution of the available energy resources between them. Analysis of production data yields the energy characteristics of the blast furnaces. Consumption figures are used to develop recommendations regarding the rational distribution of energy resources between the furnaces so as to reduce the overall coke consumption by 2.0–2.5 kg/t of hot metal. The optimal theoretical combustion temperature in all the furnaces may be derived by correlation calculations and used to determine the optimal ratio of oxygen and natural-gas consumption. In furnace operation at near-optimal temperature, the coke consumption is reduced by 0.40–0.90 kg/t of hot metal, while the productivity rises by 1.2–3.1%.
