The iron ore raw materials and coke quality is the basic reserve of improvement of the blast furnace technology. Some of the quality indicators of iron ore raw materials and coke and their influence on the main parameters of the blast furnace smelting are considered in the paper. The questions of forecasting the technical and economic indicators of the blast furnace smelting are of great importance for development the iron ore raw-material base. The industrial tests are connected with the big material and financial difficulties. Therefore we widely use the following approach: experimental measuring of the quality indicators of iron ore materials (the reducibility and durability) and coke (the reactivity), calculation of the indicators of the blast furnace smelting (the coke consumption and productivity) by means of the mathematical models. The technique of definition the minimum coke consumption in blast furnace smelting developed by us allows to calculate the reserve of coke economy.
