摘要： PURPOSE:To permit production of molten iron which permits excellent carburization, siliconization and desulfurization at a low coke ratio by using a furnace having a coke packed layer therein at the time of producing the molten iron by using inexpensive iron scrap and steel scrap as raw materials. CONSTITUTION:The furnace which has tuyeres 2 for blasting in the side wall part 1 of the furnace body, an inlet 5 for charging coke, coal and slag forming agent above the tuyeres 2, an inlet 4 for iron raw materials such as iron scrap and steel scrap, a coke inlet 5 and a gas recovering port 6 in the upper part of the furnace body, a pouring basin 15 in the lower part of the furnace body and a tap hole 7 in the side wall part is used. The coke packed layer 9 is formed on front of a combustion chamber 8 before the tuyeres 2 and an iron raw material packed layer 10 is formed above the same. The combustion gas formed in the combustion chamber 8 is passed through the coke packed layer 9 and the iron raw material packed layer 10 so as to flow upward. The iron raw materials 10 are melted by the sensible heat thereof. The exhaust gas is recovered through the recovering port 6. The molten iron and molten slag are stored in the pouring basin and are periodically extracted from the tap hole 7 to the outside of the furnace. A strong reducing atmosphere is maintained by the coke packed layer 9 in the furnace, by which the melted and formed molten iron is easily carburized and siliconized and the desulfurization reaction of the molten iron requir ing the reducing atmosphere is accelerated.

摘要： PURPOSE:To produce a molten iron with high thermal efficiency from raw materials having arbitrary grain sizes by packing ore and carbonaceous material into plural units of iron making furnaces, melting and reducing the core in one iron making furnace and preheating the ore and carbonaceous material in the other iron making furnace by the by-produced gas thereof. CONSTITUTION:The ore and carbonaceous material 6 are preliminarily packed through respective charging ports 2, 2 into plural units of the iron making furnaces A, B. The by-produced gas 10 from another suitable furnace is first introduced from a tuyere 3 into the iron making furnace A to preheat the ore and carbonaceous material 6 in said furnace and thereafter, a covered gas 9 is obtd. from a gas recovering port 4. An oxygen-contg. gas 8 is introduced into the furnace from said tuyere 3 after the end of the preheating. The carbonaceous material and ore are thereby burned, reduced and melted. While the molten iron 7 formed in such a manner is discharged together with molten slag from a tap hole 5, the gas 10 to be by-produced simultaneously is recovered from the port 4. The by-produced gas 10 is blown into another iron making furnace B from the tuyere 3 thereof to preheat the ore and carbonaceous material therein. The by-produced gas 10 is exchanged with the oxygen-contg. gas 8 after the preheating and thereafter, the above-mentioned operation is repeated.

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 save the consumption of energy, by forming the reducing gas to melt reduced iron in a melting-gasifying furnace, and reducing an iron ore into reduced iron with the reducing gas recovered from said furnace. CONSTITUTION:In a fluidized-bed reducing oven 20, a pulverized iron ore is converted into reduced iron with reducing gas recovered from a melting-gasifying furnace 1 through a line 12. Said reduced iron is formed into briquettes by a briquetting means 26 and then melted to form pig iron in the melting-gasifying furnace 1. Into this melting-gasifying furnace 1, fuel 10 based on C and H2 is blown through charging openings above tuyeres, while the same fuel 10 and O2 are blown through the tuyeres. The fuel 10 is burnt and gasified by O2 to form high-temp. reducing gas based on CO and H2. The high-temp. reducing gas is let flow upwards through a coke-packed layer and melt the reduced iron thereabove. The melted iron is let flow downwards and converted into pig iron. The reducing gas is recovered from the top of the furnace 1 and supplied to the fluidized- bed reducing oven 20.
