摘要： Vertical, parallel palisades (3) are distributed around the perimeter of a circle, spaced apart by gaps, surrounding the melt. An annular plate (4) supports the palisades (3), the palisades being provided with cavities through which a coolant flows. An induction coil (20) surrounds the palisades (3) on the outside, an alternating current flowing through the coil. The plate (4) is provided with support surfaces (4a, 4b), equal in number to the number of palisades (3), their shape conforming to the base surfaces of the palisades (3). Seen in the circumferential direction, every second support surface (4a) is covered by an electrically insulating film (7). All of the palisades (3) together are surrounded by a ring (18) of electrically insulating material, which holds the palisades (3) on the plate (4).

摘要： In a melting crucible (3) a central bottom portion (27) is formed of a plurality of palisades (5) and is shaped so that the palisades together form a vessel or a pot (7) having a centrally disposed spout or outlet (8). Two independently powered induction coils (10, 11) are provided, one coil (10) externally surrounding the collar or upper part of the central bottom portion (27), and the other coil (11) externally surrounding the spout (8). The palisades (5) are separated from one another by individual gaps (6) running radially outwardly from the center, while the electromagnetic field of at least the upper coil (10) acts on the charge contained in the melting crucible through the gaps (6).

摘要： Molds (1) with annular mold parts (2, 3) divided by at least one plane of division (E—E) and forming a plurality of cavities (8) disposed at least substantially radially to a centrifugation axis (A—A), serve for the production of precision castings by centrifugal casting, especially of parts made of materials containing titanium for internal combustion engines, the molds (1) and a casting system being contained in a closed chamber. To automate production, at least one mold part (2, 3) is made to rotate in its own rotational guide, and two mold parts (2, 3) together with the corresponding rotational guides are brought to a closed position for the casting and solidification and to an open position for the removal of the precision castings. When cast, the precision castings are preferably joined together at their radially inward pointing ends by a circumferential ring of the solidified metal and thus a circle of castings can be removed from the opened mold by a manipulating system.

摘要： A device for directional solidification of a fused metal, for example a CoCrAlY alloy, which has been poured into a molding shell, by moving the molding shell out of a heating chamber and by immersing the molding shell in a liquid-metal bath serving as a cooling melt with a lower melting-point than the fused metal in the molding shell, for example tin. The liquid-metal bath is enclosed by several current carrying toroidal coils arranged coaxially relative to one another. For the purpose of orienting the stream filament of the agitated fused metal one or more guide plates are arranged in the space between the lateral circumferential surface of the molding shell and the inner wall of the shell containing the liquid-metal bath which is located opposite the molding shell.

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.

摘要： The invention relates to a method of manufacturing directionally solidified and/or monocrystalline castings including at least one sensor for sensing temperatures in metal or allow melts contained in a mold, including a thermoelement 41 equipped with a heat resistant coating, this thermoelement being introduced into the melt. Subsequently, the position of the interface between liquidus and solidus is determined from the measured temperatures by means of interpolation, and the withdrawal speed of the casting is controlled such that during the withdrawal of the casting, the interface is always located in a desired area of the insulation 10 which slightly above the cooling head 14. For this purpose, it is advantageous that the temperature of the heating for heating up the mold be stored as a parameter in a computer over the distance covered by the mold and/or the respective position of the mold in the vacuum furnace. This heating temperature profile as a function of the respective position of the mold in the vacuum furnace in connection with the withdrawal speed of the mold is then available for further casting cycles in connection with the withdrawal speed profile as a reproducible value for subsequent casting cycles.
