  • Patent number: 4558421
    Abstract: A control system operates an automatic ladling apparatus for conveying molten metal from a furnace to a die casting machine or the like. The control system includes a plurality of adjustable speed control settings so that the speed of the apparatus can be varied according to operating conditions. The rate at which molten metal is poured into the die casting machine may also be varied. The position of the apparatus is monitored so that speed is automatically varied according to the position, and these positions are programmable. The control system includes an abort sequence to pour molten metal back into the furnace automatically if the die casting machine is not ready to accept the pour.
