    摘要: To prevent burn-back at a coal dust injection lance which projects into a hot blast conduit of a blast furnace, cooling is effected using atomized coolant. Water is preferred as the coolant. The carrier gas used for the atomized water is either air or the oxygen which is injected through the lance for complete combustion of the coal dust.

    摘要: In a process and an apparatus for the production of liquid metal (4) from fine-grain metal oxide particles, the particles, together with hot reducing gas, are blown against a heated bulk material filter layer (9) of lump coal and/or ceramic pieces, a substantial proportion of the particles being retained on and in the filter layer and subjected to finishing reducing by the reducing gas. A high-temperature flame is produced in front of the filter layer (9) by an oxygen-bearing gas being blown against the filter layer, and the metallised particles which are retained in the filter layer are melted. They pass in the liquid condition through the filter layer (9) into a receiving space (3) for liquid metal (4).

    摘要: A charging arrangement for shaft furnaces, in particular blast furnaces, comprising a container which is arranged above the shaft furnace and which is subdivided by a separating wall into a lower distributor chamber and an upper lock chamber to which the charging material can be fed from above through a filling hopper. Outside its middle and distributed around its periphery the separating wall includes at least two individually closable bottom openings through which the charging material can be passed from the lock chamber into the distributor chamber. The charging material is fed to the shaft furnace through distributor pipes which connect the distributor chamber to the shaft furnace.

    摘要: Fine ore is reduced in a circulating fluidized bed by a reduction gas in the presence of fine coal, the discharged mixture of iron sponge particles and fine coal is subjected to hot compacting and then fed to a melting vessel in which oxygen is injected into the molten material through nozzles. The melting vessel can also be supplied with scrap which has been pre-heated by the hot waste gases from the melting vessel, in a scrap pre-heater which is fitted onto the melting vessel.
