ABSTRACT:
An automatic handling system is described for delivering a molten metal, such as magnesium or magnesium alloys, to a casting machine. The handling system comprises a programmable logic controller (PLC) for monitoring and controlling the sequential delivery of shots of a precise quantity of molten metal from a furnace or holding pot to a shot delivery apparatus of the casting machine. In the preferred system, the PLC also monitors and/or controls the temperatures of the molten metal in the holding pot and in a metal transfer system, the operation of a pump for pumping molten metal from the holding pot to the shot delivery apparatus, and the level of metal in the pot, and the operation of the the casting machine.
