Abstract

PURPOSE: To solve the deficiency of raw materials and scraps and perform integrated steel making for products of higher added value by combining a shaft furnace, a cupola melting furnace, a solid carbonaceous gassifying furnace, a molten iron treating furnace and a converter.
CONSTITUTION: Iron ore and the like 6 are put into a shaft furnace 1, where they are subjected to gaseous reduction by using the gas evolved in a solid carbonaceous gassifying furnace 3. This reduced iron 7 is put into a cupola furnace 2, where it is melted by charging coke or coal Cs and quicklime C. This molten iron 8 is charged into the furnace 3, into which solid carbon K and oxygen O are blown to evolve a reducing gas G for shaft furnace. At the same time, the quicklime C is blown to desiliconize the molten iron. Thence, the molten iron is dephosphorized and desulfurized in a molten iron treating furnace 4, and further it is decarbonized in a converter 5. At this time, slag minimum blowing is executed on account of the decrease in slag amount. The deficiency of scraps S is solved by the cold charging of the reduced iron 7.
