    摘要： A method and a device for remelting metal in an electric furnace includes forming a slag bath to form molten material electrodes. The molten metal of the material electrodes solidifies in block form in a crucible apparatus as a result of cooling in such a way that a block growth forms from a block base using a progressing solidification process, wherein the block base is heated by applying energy directly to the block base to influence the cooling process.

    摘要： The invention relates to a method and to a device for sing out this method, during which the shell molds (3) are filled with a melt (11) in a clocked manner, the respectively required amount of melt being currently provided at the same time. The casting process ensues by marrying the crucible (6), which is filled with a melt (11), with a shell mold (3) so that the crucible (6) and shell mold (3) form a common cavity (10), and this arrangement is subsequently tilted 180°, so that the melt (11) falls into the shell mold (3).

    摘要： An arrangement for the regulation of the electron beam power of an electron gun, which comprises a filament cathode, a block cathode and an anode. Between the filament cathode and the block cathode is applied a first voltage, while between the block cathode and the anode a second voltage is applied. With the aid of a first closed-loop regulated system the filament cathode is regulated to a constant current value, which has a filament temperature sufficient for the maximum beam power of the block cathode. A second closed-loop regulated system, such including a block power regulator, which is acted upon by the difference between instantaneous block power value and nominal block power value, regulates the voltage between the filament cathode and the block cathode.

    摘要： For the production of particles from castings (10) of metals from the group of the lanthanides, aluminum, boron, chromium, iron, calcium, magnesium, manganese, nickel, niobium, cobalt, titanium, vanadium, zirconium, and their alloys, which have solidified in an oriented manner, especially for the production of materials from the group of magnetic materials, hydrogen storage elements (hydride storage elements), and battery electrodes, a melt of the metal is applied in a nonreactive atmosphere to the inside of an at least essentially cylindrical cooling surface (9) according to the principle of centrifugal casting. The cylinder rotates at high speed around a rotational axis, and the melt is cooled proceeding from the outside toward the inside with an essentially radial direction of solidification. The hollow casting (10) is then reduced to particles. The melt is preferably applied to the rotating cooling surface (9) in a thickness which is no more than 10%, and preferably no more than 5%, of the diameter of the cooling surface (9), and the diameter of the cooling surface (9) is at least 200 mm, and preferably at least 500 mm.
