FIELD: metallurgy; production of pig-iron.
SUBSTANCE: the invention is dealt with the field of metallurgy, in particular with smelting of a molten metal in a blast-furnace. The blast-furnace plant contains a blast furnace, a hot-air blowing installation, a charge preparation plant and a casting bed. The blast-furnace hearth diameter is from 5 up to 10 m. In the blast-furnace immediate proximity there is a compact charge preparation plant, the volume of which is intended mainly for 3-4 hours and it has the deepened loading pockets. About 25-35 meters apart from the central axis of the blast-furnace there is a conveyor with a big angle of lifting for feeding of the raw materials into the blast-furnace. The casting bed is located in the blast furnace immediate proximity. At use of the invention it is possible to significantly reduce the space of the plant and to raise economic efficiency of the pig iron production.
EFFECT: the invention allows to reduce significantly the operational space of the plant and to raise economic efficiency of the pig iron production.
