摘要： PURPOSE:To prevent the unstability of the condition of a reduction furnace by the reduction powdering of sintered ore in the stage of reducing the sintered ore in a shaft furnace in which the sintered ore is used as a raw material by preheating the sintered ore to a specific temp. or above and charging the same into the reduction furnace. CONSTITUTION:The sintered ore 18 as the iron raw material is supplied through a charging hopper 19 and a chute 20 into a preheating chamber 21. A combustion chamber 24 is provided between the chamber 21 and the reduction furnace 12 in the lower part. Oxygen and combustible gas are supplied through an inlet 28 into the furnace and is burned to the high temp. gas of about 700 deg.C so as to heat the sintered ore in the chamber 21. The sintered ore is heated to 400-600 deg.C at which the reduction powdering arises. Since the heating gas is the non-reducing gas contg. CO2 and H2O by the combustion of CO and H2, the gas enters the reduction furnace 12 without inducing the reduction powdering. The high-temp. reducing gas consisting essentially of the CO and H2 generated in the furnace 1 is supplied from a tuyere 13 to reduce the sintered ore 14 to the half-reduced iron in the solid phase. The reduced iron is then taken out of the furnace.

摘要： PURPOSE:To improve carburization, siliconization and de-sulfurization and to economically produce molten iron having good quality by blasting suitably adjusted blast temp. and oxygen concentration into a cylindrical type furnace and burning CO and H2 in the furnace gas by blowing combustible gas. CONSTITUTION:Ferrous raw material 8, coke 9, slag making agent 10, etc., are charged from furnace top raw material charging hole 1 in the cylindrical furnace. Next, the above coke 9 is burnt by blasting air 11 from tuyeres 4, to generate high temp. gas and the ferrous raw material 8 is melted by this sensible heat. The molten iron 12 and molten slag 13 thus produced are discharged from iron and slag tapping holes 5, 6 at the lower part of the furnace and the generated gas is recovered from a gas recovery hole 2 at the upper part of the furnace. In this above iron-making process, assuming that CO2/(CO2+ CO) and H2O/(H2O+H2) is gas generated by combustion of the coke 9 both become zero, the blast temp. and the oxygen concentration are adjusted to blast, so that the blast temp. rises to >=2,000 deg.C. Further, the combustible gas 14 is blown from a blowing holes 7 in the furnace side wall part 3 at the upper part of tuyeres 4, to burn CO and H2 in the furnace gas, and the charging materials are heated by the sensible heat.
