发明名称 Process and apparatus for the production of particles from castings which have solidified in an oriented manner
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.
