In the blast furnace with a hearth diameter of 8.4 m the effect of slag output on coal-burning rat and furnace capacity was investigated. The relation between the relative slag ratio and productivity was not found. The dependences of the coke consumption, fuel and smelting rate defining by the total carbon is found out; all these components are defined by the slag amount, which depends on iron content change of melting furnace-charge. It is shown that under current conditions of smelting process the furnace can operate with the slag output up to 1150-1200 kg / t of pig iron.
