摘要： A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).

摘要： An apparatus with a vessel (20), a first induction source (30), and a second induction source (32) in the melt zone (12). The first induction source (30) is used to melt the material received in the vessel (20).

The coils (26) of each of the first and second induction sources (30, 32) can be arranged such that they intertwine in an alternate fashion or that they are in sets in a series. The coils (26) of the sources (30, 32) can also sequentially receive power such that the material is moved through the ejection path after melting and into an adjacent mold. The vessel (20) can be positioned along a horizontal axis (X). The apparatus can be used to melt and mold amorphous alloys; for example.

摘要： Various embodiments provide apparatus and methods for melting materials and for containing the molten materials within melt zone during melting. Exemplary apparatus may include a vessel configured to receive a material for melting therein; a load induction coil positioned adjacent to the vessel to melt the material therein; and a containment induction coil positioned in line with the load induction coil. The material in the vessel can be heated by operating the load induction coil at a first RF frequency to form a molten material. The containment induction coil can be operated at a second RF frequency to contain the molten material within the load induction coil. Once the desired temperature is achieved and maintained for the molten material, operation of the containment induction coil can be stopped and the molten material can be ejected from the vessel into a mold through an ejection path.

摘要： Apparatus and method are provided for electric induction heating and melting of a transition material that is non-electrically conductive in the solid state and electrically conductive in the non-solid state in an electric induction heating and melting process wherein solid or semi-solid charge is periodically added to a heel of molten transition material initially placed in a refractory crucible. Induction power is sequentially supplied to a plurality of coils surrounding the exterior height of the crucible at high power level and high frequency with in-phase voltage until a crucible batch of transition material is in the crucible when the induction power is reduced in power level and frequency with voltage phase shifting to the induction coils along the height of the crucible to induce a unidirectional electromagnetic stir of the crucible batch of material.

摘要： An apparatus and process are provided for controlling the heating and melting of a material that is non-electrically conductive in the solid state and is electrically conductive in the non-solid state. Power is selectively directed between coil sections surrounding different zones of the material in a susceptor vessel by changing the output frequency of the power supply to the coil sections. Coil sections comprise at least one active coil section, which is connected to the output of the power supply, and at least one passive coil section, which is not connected to the power supply, but is connected in parallel with a tuning capacitor so that the at least one passive coil section can be selectively operated at, or near, resonant frequency when the transition material in the vessel is molten. Depending upon the state of the transition material in the susceptor vessel, the frequency of the power applied to the active coil section can be changed to generate a magnetic field that selectively couples with the susceptor vessel, transition material in the vessel, and/or the passive coil section.

摘要： It is an object of the present invention to prevent temperature decrease in a border portion of each of heating coils and to enable to eliminate an influence given by the change in a load state. In order to attain this object, an induction heating unit according to the present invention is provided with control units respectively corresponding to a plurality of heating units. A phase detector of the control unit obtains a phase difference between an output current (heating coil current) of an inverter detected by a current transformer reference signal outputted by a reference signal generating section, and inputs it to a drive control section. The drive control section adjusts an output timing (phase) of a gate pulse to be given to the inverter so as to make a phase of the heating coil current of the inverter coincide with a phase of the reference signal outputted by the reference signal generating section. A phase control section controls a variable reactor so as to make the phases of an output voltage and the output current (heating coil current) of the inverter coincide with each other, and improves a power factor of the inverter. Each of the other control units also performs the same control operation.

摘要： The present invention generally relates to a high-frequency pulse oscillator, and more particularly to a high-frequency pulse oscillator adapted to provide pulse currents having a high frequency and large amplitude so as to transition metallic materials into a plastic state for ease of processing or for closing microcracks formed in metallic parts in order to recover mechanical characteristics thereof. The high-frequency pulse oscillator of the present invention comprises a controllable rectifier, a switching section, and a control system. The controllable rectifier rectifies alternating currents supplied from a current source to output currents having a predetermined waveform, according to a control signal from the control system. The switching section generates pulse currents using the currents from the rectifier, according to another control signal from the control system. The switching section comprises at least one switching block, which is connected so that the amplitude of the pulse currents is increased. The control system controls the rectifier and the switching section according to the signals to start, stop, and reset the operation of generating the pulse currents and the signals to specify or change the frequency and amplitude of the pulse currents, so that the generated pulse currents may have desired frequency and amplitude. The pulse currents generated in the high-frequency pulse oscillator enable the manufacture of various structural parts without degrading their structure.

摘要： Methods of operation of an induction melter are disclosed. Particularly, a cooled crucible and an inductor may be provided proximate thereto for heating at least one material therein. A desired electromagnetic flux skin depth for heating the at least one material within the crucible may be selected and a frequency of an alternating current for energizing the inductor therewith and for producing the desired skin depth may be selected. The inductor may be energized with the alternating current having the selected frequency. Optionally, the frequency of the alternating current may be selected in response to a difference between a desired skin depth and the indicated skin depth. The desired skin depth may be selected to be about 38% of a diameter of the at least one material. The desired skin depth may be substantially maintained as the temperature of the at least one material varies.
