    The invention relates to the field of ferrous metallurgy, to devices for the direct reduction of iron oxides to liquid metal. The purpose of the invention is to increase the efficiency of the shaft furnace. The installation consists of a gas generator 1 and a shaft reduction furnace 2 located above it, which is connected to the gas generator by coupling shaft 6, thus making it possible to directly introduce the regenerating gas obtained in the gas generator with its high dust content due to the fact that the sponge the iron is introduced by means of several radially arranged augers 11, and a restoring fas is inserted into the annular gap 7 above the feeding augers. The use of the invention significantly increases the efficiency of the shaft furnace. 9 3. п. Ф-лы ,, 5 Il. gz chzaev
