The invention relates to the ferrous metallurgy, in particular, to the blast-furnace production and can be used in smelting of cast iron in blast-furnaces, working under different pressure of top smoke with inflation or without inflation of additional carbonaceous fuel into the blast-furnace hearth. A method for blast-furnace running involves measuring and adjustment of rate of blowing and top gas, at that the forcing level of blast furnace running relatively to reduced blast input is carried out by increasing the ratio of top gas pressure to the differential of «tuyeres-blast-furnace top» pressure.
