The vacuum induction melting system is designed to be operated in a continuous or semi-continuous manner for extended periods of time for increased efficiency, and makes it possible to easily and quickly remove the induction furnace from the melt chamber when it becomes necessary to replace and rebuild the furnace. The melting system includes a melt chamber which forms an airtight enclosure, with an induction furnace located within the melt chamber. A charging chamber is communicatively connected to the melt chamber adjacent its upper end. The charging chamber includes a door providing access to the interior of the charging chamber so that a charge of raw materials can be placed therein. An isolation valve is located between the melt chamber and the charging chamber and is movable between open and closed positions. A mold tunnel is connected to the melt chamber adjacent its lower end, with the mold tunnel including a pour opening which communicates with the melt chamber and through which molten metal poured from the furnace can enter the mold tunnel. A mold carriage is positioned within the mold tunnel for receiving and carrying one or more molds adapted for receiving molten metal. An isolation valve is located between the melt chamber and the mold tunnel and is movable between an open and a closed position. A mold transport assembly is provided for moving the mold carriage from a pouring position within the mold tunnel to a loading position located outside of the mold tunnel.
