摘要： The invention relates to a method for reducing the chrome content in metallurgical slags, whereby the slags are fed in liquid form into an iron bath and Cr reduction occurs with the aid of the iron bath with a C content of 2 to 4 weight percent, wherein a) the Cr-containing slag with a Cr content of 2 to 20 weight percent is fed into an iron bath with a C content of less than 1 weight percent, whereupon b) the carbon content of the iron bath is raised to approximately 2 to 4 weight percent by adding C carriers and simultaneously supplying energy, c) the liquid slag with a Cr content of approximately 0.1 weight percent is tapped after Cr reduction, d) a cooling medium, preferably scrap, is added to the iron melt and the C content of the melt is lowered to less than 1 weight percent and e) part of the liquid Cr-containing melt is tapped while the remainder is preserved in liquid form in the converter for the treatment of subsequent melts.

摘要： The invention relates to a facility for melting materials and/or dusts that have already been reduced in size, such as for example furnace or steel dusts, marl and lime dust mixtures, light shredder fractions and/or waste materials that have been reduced in size, wherein the material or the dusts are injected into a combustion chamber together with a carrier gas. The dusts or the material are introduced into a cyclone (3) in an axial relation and the carrier gas is introduced in a tangential relation thereto. The cyclone (3) is linked with a combustion chamber (8) via a substantially axially aligned discharge opening (9).

摘要： The invention relates to a method for the thermal processing of residues containing heavy metals and iron oxide, designed for use in a multiple-hearth furnace which comprises several hearths positioned on top of each other. According to said method residues containing heavy metals and iron oxide are continuously fed to the multiple-hearth furnace such that they are introduced into the topmost hearth and gradually transferred to the lower hearths. Reducing agents are introduced into the topmost and/or one of the lower hearths and react with the residues containing heavy metals and iron oxide such that heavy metals and directly reduced iron are produced. The heavy metals are discharged from the furnace with the waste gases and the iron is discharged together with reducing agent residues in the area of the lowest hearth of the multiple-hearth furnace.

摘要： To produce pig iron or steel and cement clinker from slags, it is proposed that liquid slags containing iron oxide, e.g. slags from steelworks, should be converted with iron oxide carriers (such as ore, scales or similar materials) and lime to produce a ferrite-containing slag which is then introduced into a reduction reactor (such as an iron bath reactor) for reduction. The sintered phase is subsequently removed in the form of clinker.

摘要： A method of solidifying a steel-making slag is performed by subjecting a mixture of a steel-making slag containing at least about 50% by weight of a powdery steel-making slag having a particle size not greater than about 5 mm and a substance containing at least about 30% by weight of SiO 2 (e.g., a fly ash and/or the fine powder of a granulated blast furnace slag) to a hydration reaction. The resulting solidified material contains at least about 20% of a tobermorite phase, has high strength and is suitable as an inorganic material useful as a roadbed material, building and civil engineering materials, etc.

摘要： Steelworks dusts or sludge is mixed into sewage preferably in the presence of a flocculating agent to provide a rapid separation of a clear effluent and a sludge which is dewatered and dried to form a solid material adapted to entrap harmful materials in the sewage such as heavy metals, pathogens and organic chemicals. The solid material is supplied to a smelt reduction furnace from which molten iron is recovered and a hot gas discharge is provided from which recovery of zinc and other materials may be achieved, other waste material being removed as a slag.

摘要： In the manufacture of fuel gas or synthesis gas by partially combusting carbonaceous fuel, preferably solid carbonaceous fuel having a high content of non-combustible constituents, finely divided fuel is injected into a shaft-like reactor chamber (10) and is combusted partially while moving down through the reactor chamber, to form a fuel' gas or synthesis gas which is removed from the reactor chamber at the upper part (12) thereof, while simultaneously melting non-combustible constituents of the fuel, the resultant melt being taken out of the reactor chamber at the bottom part (13) thereof. A layer (32) of molten material which covers the wall (11) of the reactor chamber and moves downwardly along the wall is sustained by maintaining a selected temperature for substantially instantaneous melting of the non-combustible constituents of the fuel, and by selecting the directions in which the fuel is injected into the reactor chamber so that at least a substantial part of the fuel or the non-combustible constituents contained therein is brought into contact with the wall (11) of the reactor chamber or the layer (32) on said wall during movement down through the shaft. The wall of the reactor chamber is kept cooled in order to maintain thereon, between the wall and the molten layer (32), a frozen coating (33) formed by the non-combustible constituents of the fuel and protecting against slag attack and overheating.
