摘要： The invention relates to a device and a method for supplying heat to a metal melt, where in a closed container (11) with openings (13,14) for supply and discharge of the melt and where a sub pressure may be formed, a rotor (16) in the form of a hallow rotation body and a hollow driving shaft (20) containing the electrode (23) for supply of electric current for formation of an electric arc (34) towards the surface (31) of the metal of the melt. The lower end of the electrode (23) is positioned in a hollow head with an opening (35) downwards towards the bottom of the container (11). The hollow head is configured to provide access to the surface (31) of the metal melt, so that the electric arc (34) is formed inside the head and where the hollow driving shaft (20) possibly is configured for supply of gas to the metal melt. The lower end surface of the rotor (16) is configured so that a pumping effect in the heated melt beneath the lower end of the rotor (26) is formed, moving the heated melt sideways away from the rotor (16) along the lower, external end surface of the rotor (16).

摘要： A configurable baffle to configure fluid flow through a nozzle. To improve the quality and accuracy of processing apparatus used in the cutting, welding, and heat treating of materials, a self-aligning nozzle includes a configurable baffle. This configurable baffle can be a metallic grid (e.g., a screen) or other type of membrane (e.g., porous, permeable, etc.). During its initial use in the processing apparatus, this configurable baffle is tailored with an energy beam, such as a laser beam or plasma jet, to create an optimal fluid flow velocity profile. When the configurable baffle deteriorates from use, it is easily replaced by another baffle or by using an in situ replacement mechanism. To ensure proper alignment between the nozzle and the energy beam, mating contoured surfaces are used among adjacent components. Threaded surfaces can also be employed to assist in achieving the proper coaxial alignment.

摘要： The invention relates to a device (5) for producing a quartz glass crucible (2). At least two electrode arrangements (7, 8) which are evenly distributed on the periphery of the quartz glass crucible (2) and which produce a first arc and an additional arc each heat a section (14, 15) of a wall (13) of the quartz glass crucible (2), which rotates during this process. The use of multiple electrode arrangements (7, 8) enables the period in which the sections (14, 15) cool off before reaching the next heating area (11, 12) to be shortened, which in turn prevents an undesirable considerable temperature difference in the wall (13). At the same time, the necessary heat output for each individual electrode arrangement (7, 8) can be reduced, which reduces evaporation phenomena and the bubble formation that is associated with this. This not only improves quality but also shortens the production process.

摘要： The present invention is concerned with a method for the production of fine and ultrafine powders of various materials such as metals, alloys, ceramics, composites etc., through a transferred arc plasma system. The method comprises vaporizing or decomposing the material in the plasma reactor, condensing the vapor in a quench tube comprising two sections, the first one for indirectly cooling or heating the vapor, and the second one for directly cooling the vapor. The powder is recovered in a conventional collection unit. The two step condensation in the quench tube allows a substantial control of powder properties like crystallinity, size distribution and mean particle size.
