    摘要： The invention relates to a method for injecting reducing agents into a shaft furnace in which the reducing agent is transported within a pneumatic delivery stream to the shaft furnace according to the following steps; a) dividing the delivery stream into a number of partial streams, b) transferring the individual partial streams through a heating unit, and c) heating the reducing agent within the individual partial streams inside of the heating device. A device for carrying out the inventive method comprises, for example, a delivery line in order to pneumatically deliver the reducing agent to the shaft furnace, and a number of heat exchange pipes which are integrated in the delivery line using a parallel connection, said connection relating to flow techniques, such that the pneumatic delivery stream is divided into a number of partial streams. The inventive device also comprises a heating unit for transmitting heat energy to the individual partial streams.

    摘要： A method of operating a shaft furnace charging an iron source containing sheet scrap iron in 50 mass% to 90 mass% and coke in alternating layers over a coke bed filled inside a furnace lower portion from the furnace top and blowing air from tuyeres at the lower portion of the furnace to melt the iron source, comprising (a) dividing the sheet scrap iron of each charge in a raw material charging bucket into two so that the ratio of the sheet scrap iron after division to the total amount of the iron source becomes no more than 50 mass% in each portion, (b) inserting between the divided portions of sheet scrap iron at least one material of plate scrap iron, an iron source other than scrap iron, or coke, then (c) charging the furnace interior via the raw material charging bucket with the divided sheet scrap iron and any of the plate scrap iron, iron source other than scrap iron, or coke in alternating layers.
