A system and method for sensing the position of an ingot within a segmented mold of a vacuum metallurgical system. An inductive sensory system measures the variations in current between a power source and load of an induction heating coil. The system and method is particularly suitable for determining the position of an ingot within a melting system mold where the mold has a relatively reduced or small cross-sectional area.
A system and method for sensing the melt level of an ingot and/or molten material within one or more of a melting hearth, a refining hearth, tundish, and/or a casting mold within a furnace system. One or more laser melt height systems is configured and oriented to measure the melt level of one or more furnace system vessels within a closed furnace chamber, and thereby provide control information for regulating an overall melting, refining, casting, and /or atomization process.

A puller head mold for receiving molten metal or alloy during the casting of an ingot, the puller head mold having a tapered screw thread structure. The tapered threaded puller head is used to pull and withdraw a cast ingot from a casting furnace, and can be particularly useful for the handling of ingots having a relatively narrow diameter. The tapered threaded puller head profile provides for full release of the tapered threaded puller head from a cast ingot in a fraction of a turn. The size and profile of the cast ingot formed with the tapered threaded puller head is resilient to thermal gradients while cooling.

A furnace system for melting and casting metals, alloys, and superalloys and a related method. A melt chamber of the furnace system is configured and arragned to include at least two melt boxes, thereby increasing the volume of alloy charge that can be rendered molten during a single furnace heating cycle. Accordingly, a number of ceramic casting molds equal to the number of melt boxes can be used to form castings following a single furnace heating cycle. The ceramic casting molds can be pre-heated in an external oven before being introduced to the mold or loading chamber of the furnace system. The throughput of the furnace system is increased by the ability to pour more than one casting per alloy charge melting cycle.
A method and a system for forming a solid casting. A material is fed into a mold having a retractable bottom. A first portion of the material at a first, lower position within the mold is allowed to solidify to thereby form a portion of the casting. The retractable bottom is withdrawn downwards at a withdrawal rate. A second portion of the material at a second, upper position within the mold is maintained in a liquid state by application of heat thereto, using a plasma arc generated by a plasma arc torch. A voltage of the plasma arc is measured, and the withdrawal rate of the retractable bottom is controlled based on the voltage of the plasma arc.

A system and method for melting a raw material. The raw material is fed into an electrically conductive vessel. A plasma arc torch melts at least some of the raw material within the vessel to thereby create a molten material. An inductor, physically disposed adjacent the vessel, and electrically disposed in series with the vessel in operation, effects electromagnetic stirring of the molten material by interacting with the current of the plasma arc torch.
