    摘要: Method and apparatus for processing reduced iron in which granular iron oxide charged into a vertical furnace is reduced by a reducing gas comprising mainly carbon monoxide and hydrogen, a substantial portion of the waste gas generated in the reduction process being regenerated in a recirculating system. The reduced iron which has been reduced in the vertical furnace is continuously discharged at a temperature above 500.degree. C under isolation from the exterior atmosphere and is received in a plurality of air tight, sealable component adjusting receptacles. The reduced iron received in the receptacles is subjected to component adjustment at a temperature ranging from 700.degree. to 1100.degree. C by using the regenerated reducing gas and, thereafter, it is discharged from the receptacles under isolation from the exterior atmosphere so as to be received in air tight sealable cooling receptacles thereby cooling the same to a temperature lower than 100.degree. C, the reduced iron being thereafter discharged from the receptacles.

    摘要: A furnace product is permitted to flow out by gravity from the opening defined between the lower end of a furnace wall and a furnace bottom and to accumulate on the circumferential portion of the furnace bottom with a reposing angle inherent to the product, with the accumulation being drawn out of the furnace from the circumferential portion of the furnace bottom. The furnace bottom is formed with a diameter larger than the inside diameter of the lower end of the furnace wall and vertically spaced from the lower end of the furnace so as to provide an opening therebetween through which the furnace product is allowed to pass a discharging device comprising a reciprocating raking arm with its end movable across the circumferential portion of the furnace bottom operates to remove product therefrom.
