摘要： 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.

摘要： Apparatus and method are provided for heating and melting of materials by electric induction heating of susceptor components in a crucible of the furnace. The susceptor components comprise at least an array of susceptor rods arranged around the inner perimeter of the crucible. A susceptor base may also be provided in the crucible with connection to one end of the susceptor rods. One or more susceptor tubes may also be used within the interior volume of the crucible. Alternating current flow through one or more induction coils surrounding the exterior of the crucible generate magnetic flux fields that couple with the susceptor components to inductively heat the susceptor components. Heat from the susceptor components transfers to the material in the crucible to heat and melt the material.

摘要： A current fed inverter with duty cycle regulation of dc current to the input of the inverter is provided to increase the magnitude of inverter output power while operating a resonant load at resonant frequency. The regulator duty cycle period is synchronized to the period of the output current of the inverter so that there are two regulator periods for each single output current period of the inverter. Duty cycle regulation may be provided by a single pulse in the regulator period, or a series of pulses in the regulator period. Output power magnitude greater than that available at full duty cycle can be provided by operating the inverter at off resonance. Multiple current fed inverters may be connected to individual coil sections around a crucible and selectively interconnected for a heating or melting mode, or a stir mode.

摘要： Molten metal, or other electrically conductive material, in a vessel can be inductively heated, and simultaneously inductively stirred. A single-phase ac supply provides induction heating power to at least one set of three induction coil sections surrounding the vessel. A three-phase ac supply provides induction stirring power to at least one set of three induction coil sections surrounding the vessel. The single-phase ac supply is capacitively connected to the coil sections to form a heat resonance circuit, and the three-phase ac supply is inductively connected to the coil sections to form a stir resonance circuit. The heat circuit capacitive elements provide a sufficient impedance to the output of the three-phase ac supply to block power transfer from its output to the input of the single-phase supply. The stir circuit inductive elements provide a sufficient impedance to the output of the single-phase supply to block power transfer from its output to the input of the three-phase supply.

摘要： An induction furnace system has an active induction coil surrounding a crucible. A passive induction coil also surrounds the crucible. The passive induction coil is connected in parallel with a capacitor to form an L-C tank circuit. A source of ac current is provided to the active induction coil to produce a magnetic field that inductively heats and melts an electrically conductive material in the crucible. The magnetic field also magnetically couples with the passive induction coil to induce a current in the passive induction coil. This induced current generates a magnetic field that inductively heats and melts the material. The resistance of the L-C tank circuit is reflected back into the circuit of the active induction coil to improve the overall efficiency of the induction furnace system. The crucible may be open-ended to allow the passage of the electrically conductive material through the crucible during the heating process.

摘要： An induction furnace which provides a controlled escape pathway for superheated metal is disclosed. The induction furnace comprises a base layer of refractory material in the bottom of the furnace vessel. The base layer of refractory is composed of a first refractory having a maximum operational temperature and a second refractory having a maximum operational temperature lower than that of the first refractory. At least a portion of the second refractory is arranged in a contiguous zone through the thickness of the base layer. The base layer supports a packed granular refractory lining that extends up along the side wall of the vessel. In one embodiment of the invention, the base layer takes the form of a means for pushing out the packed granular lining from the furnace. The pusher means is arranged for axial movement within the furnace in response to a driving force applied from below the base layer. The pusher means contains the contiguous zone of the second refractory. In another embodiment of the invention, the base layer is comprised of tiers of refractory, each tier comprising a portion of the second refractory in the same location as in each other tier forming a contiguous zone of the second material. The failure of the second refractory zone allows the superheated metal to escape through the base of the furnace in a controlled manner at the preselected location of the second zone.
