摘要： 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.

摘要： 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.
