Abstract: A method for operating an electric arc furnace having at least one electrode, the method including the following steps: introducing material that is to be melted in the form of an actual mass flow into the electric arc furnace and feeding electrical energy via at least one electrode into the electric arc furnace in order to melt the introduced material depending on a previously determined, necessary electrical energy input. The necessary electrical energy input into the arc furnace is determined depending on the mass flow input into the furnace.

Abstract: A method for automatic calculation of a pass schedule in the radial forging of steel tubes in a radial forging machine is disclosed. The forging machine includes at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted for synchronous forging operation over at least a partial length of the workpiece and/or the tube. Starting parameters for the forging process, preferably radial forging process, are entered into a pass plan calculation program and target parameters for the radial forging process are defined. The pass plan calculation program calculates a pass plan or a forging sequence on the basis of these start and target parameters.

Abstract: A method and a device for determining the material properties of a polycrystalline, in particular metallic, product during production or quality control of the polycrystalline, in particular metallic, product by means of X-ray diffraction using at least one X-ray source and at least one X-ray detector. In this case, an X-ray generated by the X-ray source is directed onto a surface of the polycrystalline product and the resulting diffraction image of the X-ray is recorded by the X-ray detector. After exiting the X-ray source, the X-ray is passed through an X-ray mirror, wherein the X-ray is both monochromatized and focused, by the X-ray mirror, in the direction of the polycrystalline product and/or the X-ray detector, and then reaches a surface of the metallic product.

Abstract: The disclosure relates to a method for operating a cooling chamber in a strand guide device and the strand guide device 10 as such. The strand guide device serves to deflect a freshly cast strand, typically made of metal, into the horizontal. During the deflection, the cast strand passes through a cooling chamber 1 inside the strand guide device 2, in which it is sprayed with a coolant 33, with the formation of steam 5. The steam forms at least a steam-air mixture 5′ with sucked-in secondary air, which is sucked out of the cooling chamber by a suction device 20. In particular, in order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture 5′ and its emission into the environment, the present invention provides for pollutants, primarily dust, located in the steam-air mixture 5′ by a separator 6, 6′ to deplete.

Abstract: A cooling device for cooling a material to be cooled, comprising an inlet for a cooling medium conducted into a first, upper chamber of the cooling device. First conduits are provided which conduct the cooling medium from the upper chamber into a second, lower chamber of the cooling device. The upper chamber is separated from the lower chamber by a wall. Second conduits are provided which conduct the cooling medium from the lower chamber to at least one outlet opening for cooling medium, via which the cooling medium is discharged onto the material to be cooled.

Abstract: A method for treating molten metals (4) and/or slags in metallurgical baths comprises the introduction of a process gas into a melt bath. The process gas is accelerated to supersonic speed and is introduced below the melt bath surface (5) by means of at least one supersonic nozzle (6) with supersonic speed into the liquid phase of the molten metal (4) and/or into the slag and/or into the region of a phase boundary between molten metal and slag. The disclosure further relates to a metallurgical plant for treating molten metals.

Abstract: A method of treating cooling circuit water of industrial plants (2) contaminated with organic substances and inorganic particles, comprises the following steps: a) separating the organic substances and inorganic particles from the cooling circuit water to obtain precleaned cooling circuit water; b) cooling the precleaned cooling circuit water by an open cooling tower (11) to obtain cooled precleaned cooling circuit water; c) desalinating at least a partial volume flow of the cooled precleaned cooling circuit water by an desalination plant (14) to obtain cleaned cooling circuit water; and d) adding bacteria capable of degrading organic substances present in the cooling circuit water. The bacteria are added to the cooling circuit water before the separation in accordance with step a), before the cooling in accordance with step b) and/or before the desalination in accordance with step c), to form a biological cleaning stage.

Abstract: In a method for producing a spray nozzle device, in particular for spraying a casting strand during casting of metallic products, the spray nozzle device includes a basic body with an air inlet, a water inlet and a nozzle body with a mixing chamber for producing an air/water mixture which emerges through at least one nozzle outlet. The air inlet is formed by at least one air inlet nozzle, with a nozzle tip projecting into the mixing chamber, and has at least one air outlet hole. The water inlet opens into the mixing chamber close to the nozzle tip of the air inlet through at least one water outlet hole oriented transversely to a longitudinal axis of the mixing chamber. At least one part region of the spray nozzle device is produced by a generative production process, preferably operating as a 3D printing process.
