HIGH EFFICIENCY INDUCTION MELTING SYSTEM

摘要

An induction melting system (78) uses a crucible (50) formed from a material that has a high electrical resistivity or high magnetic permeability and one or more inductor coils (52) formed from a wound cable consisting of multiple individually insulated copper conductors to form an induction furnace that, along with its associated power supply, provides a compact design. The system components are air-cooled; no water-cooling is required. The induction melting system is particular useful for separating metal from scrap (79), casting molds directly from the induction furnace, and providing a continuous supply of molten metal. The induction system may also be in the form of a tunnel or enclosed furnace for heating a workpiece.
