UNEVENLY SPACED INDUCTION COIL FOR MOLTEN ALLOY CONTAINMENT

摘要

Various embodiments provide an apparatus and methods for containing the molten materials within a melt zone during melting. The apparatus may include a vessel configured to receive a material for melting therein and an induction coil with unevenly spaced turns along its length. Induction coil can have a series of turns acting as a first (e.g., load) induction coil and a series of turns acting as a second (e.g., containment) induction coil. The material in the vessel can be heated and contained by the separated turns of the induction coil. A plunger can also assist in containing material during melting. Once the desired temperature is achieved and maintained for the molten material, operation of the induction coil can be stopped and the molten material can be ejected from the vessel into a mold using the plunger.
