摘要： The invention discloses a process and a device for producing liquid metal (4) from fine metal oxide particles. The metal oxide particles, together with a hot reducing gas, are blown against a heated bulk materials filter layer (9) consisting of lumps of coal and/or ceramic parts. A substantial proportion of the particles are retained on and in the filter layer and completely reduced by the reducing gas. An oxygen-containing gas is blown against the filter layer (9) to produce a high-temperature flame in front of the filter layer, and the metallized particles retained in the filter layer are melted. These liquefied particles pass through the filter layer (9) into a collecting chamber (3) for liquid metal (4).

摘要： The invention concerns a process and device for gasifying liquid and/or fine-particulate solid materials and/or for reforming a gas, with the addition of a gasification agent, in a reactor (1). In this process, the heat is supplied by heat-carrier particles which are heated in a heater (5) by combustion gases produced in a combustion chamber (3), then passed, flowing in the opposite direction to the material being gasified/gas being reformed plus gasification agent, through the reactor (1), and subsequently fed back in an essentially closed circuit to the heater (5) for reheating. The invention calls for the particles and the combustion gas to form a fluidized bed above at least one grid (34, 34a, 34b, 34c, 34d, 34e) fitted in the heater (5). The particles flow out of the heater (5) into the combustion chamber (3) next to it where they form, together with the combustion gas, a fluidized bed, subsequently passing out of the combustion chamber (3) through an overflow pipe (7, 7') which carries them into the upper zone of the reactor (1). The passage of the particles through the overflow pipe (7, 7') compresses the particles, which prevents the gaseous products produced in the reactor (1) from escaping through the pipe. In the reactor (1), the particles form one or more fluidized beds together with the material being gasified and/or gas being reformed.

摘要： In order to heat sponge iron up to temperatures of about 850 °C without substantial oxidation losses, the sponge iron is successively supplied to at least two separate pre-heating stages with different temperatures and in which the temperature and the gaseous atmosphere are individually controlled so that in the first pre-heating stage having the lowest temperature a chemically neutral gaseous atmosphere is set and in the last pre-heating stage having the highest temperature a reducing gaseous atmosphere is set. The hot gas for the pre-heater is taken at least partially from the waste gas of the melting furnace to which the pre-heated sponge iron is supplied.

摘要： The invention concerns a nozzle assembly for introducing fluids into a melt, the nozzle assembly comprising a perforated nozzle brick (3), made of refractory material, which can be inserted in the wall (1) of the melt vessel (2) and which surrounds a cylindrical element (4) holding a nozzle tube (6, 7). In order to increase the useful life of the nozzle assembly, the cylindrical element (4) is surrounded by the nozzle brick (3) so that it can move longitudinally, and the nozzle tip is replaced, as it is consumed, by pushing the cylindrical element (4) in towards the interior of the melt vessel.

摘要： In order to avoid burn-back in a coal-dust blowing lance which projects into the hot-blast main of a blast furnace, the lance is cooled with a coolant aerosol. Water is the preferred coolant. Either the oxygen blown in through the lance to ensure complete combustion of the coal dust or air is used as the carrier gas for the water aerosol.

摘要： For the metallurgical treatment of a metal melt (1) in a metallurgical smelting and fining vessel (3), free-flowing additives (43), especially lime, are added in granular to powder form at least during part of the fining stage in the upper region of the inside (15') of the vessel wall (11), distributed about the circumference. The additives (43) form a blocking or protective layer on the vessel wall (11) by means of which power losses are reduced and the useful life of the vessel (3) is prolonged.

摘要： For the purposes of transferring a predetermined amount of liquid metal from a vessel (1) containing a molten metal bath (2) into a receiving container (3), there is provided a discharge flow pipe (4) which has a refractory lining and which is in the form of an inverted U or V with two downwardly pointing limbs (5, 6) of which the first has an intake opening and the second has an outlet opening for the liquid metal, which outlet opening can be gas-tightly closed by a closure means. Provided in the upper region of the discharge flow pipe (4) is a pipe connection (14) which has a refractory lining and which can be communicated with a vacuum means (19, 20). The discharge flow pipe is dipped with its first limb (5) into the molten metal bath (2) and the liquid metal is removed on the basis of the principle of a liquid siphon.
