Abstract: A cold crucible usable in the field of high-temperature production of monocrystalline materials. The cold crucible includes: a cold cage which has sectors made of a material having good electrical conductivity and in which a charge is melted, and a cooling device with heat transfer fluid, configured to cool each segment of the cold cage from the inside. The cold crucible is essentially such that it further includes at least one device for generating a static magnetic field, each generating device being housed inside one of the sectors of the cold crucible. Each static magnetic field thus generated having the effect of slowing down the electromagnetic stirring of the molten charge, such that it is possible to produce monocrystalline ingots of significantly larger diameter than the diameter of the seed initiating their growth.

Abstract: The functional condition of an induction crucible furnace is checked by first establishing a set-point parameter corresponding to an optimum functional condition of the induction crucible furnace and characterizing the vibratory behavior of same. Then, during normal operation of the furnace, an actual-value parameter of the vibratory behavior is determined. These two parameters are then compared and, if a magnitude of a difference therebetween exceeds a threshold, an alarm is generated.

Abstract: The product of a molten alkali metal metalate phase separation can be processed into a purified metal from a metal source. Metal sources include native ores, recycled metal, metal alloys, impure metal stock, recycle materials, etc. The method uses a molten alkali metal metalate as a process medium or solvent in purifying or extracting high value metal or metal oxides from metal sources. Vitrification methods using the silicate glass separation phase can be prepared as is or can be prepared with a particulate phase distributed throughout the silica glass phase and encapsulated and fixed within the continuous glass phase. Tungsten metal can be obtained from an alkali metal tungstate. A typically finely divided tungsten metal powder can be obtained from a variety of tungsten sources including recycled tungsten scrap, tungsten carbide scrap, low grade tungsten ore typically comprising tungsten oxide or other form of tungsten in a variety of oxidation states.

Abstract: The present invention is apparatus for, and method of, heating, melting and purifying a material by electric induction heating in a susceptor furnace. Non-electrically conductive solid charge may initially be placed in the furnace. Output frequency from a power source supplying current to one or more induction coils surrounding the furnace is selected to maximize magnetic coupling with the susceptor material in the susceptor furnace to induce eddy current heating in the material. Heat transfers by conduction from the susceptor material to the non-electrically conductive charge placed in the susceptor furnace to melt the charge. Output frequency is reduced as the charge melts and becomes electrically conductive to enhance magnetic coupling with the melt in the furnace. Degassing of impurities from the melt can be achieved by bubbling a gas through the melt while the surface level of the melt is maintained at vacuum. Degassing is enhanced by creating an electromagnetic ripple/wave action that increases the surface area of the melt during the degassing process.

Abstract: An induction heating device which raises the temperature of a metal to be heated for one of melting or hot machining while providing considerably energy saving, increasing yield and observing current safety standards. The device (10) uses a cavity (11) to receive the metal to be heated and at least two magnetic yokes (13) arranged around a periphery of cavity (11), each yoke supporting an independent induction coil (14). The induction coils are mounted and wound in the same direction such that a north pole, of each coil, is located on one side of the cavity and a south pole is located on an opposite side of the cavity. The inductive coils are arranged so as to generate active non null magnetic field zones and inactive zones of null magnetic fields distributed about the periphery of the cavity. An inactive zone of null magnetic fields is located between each adjacent active non null magnetic field zone. The induced current is self-enclosed thereby producing high heating power and the invention is applicable to melting, forging, reheating, transforming, and working metals by induction.
