The teachings provide a fill tube assembly for a casting mold and methods of using the assembly. The fill tube assembly includes a fill tube having a tubular member with a receiving end, a mold-engaging end and an intermediate portion. The mold-engaging end has a tapered flange radially extending therefrom, the remainder of the tubular member has a substantially, uniform cross-section. A clamping assembly is structured to maintain a substantially leakproof seal at the fill tube, casting mold interface while accommodating dimensional variations. The clamping assembly includes a gasket, a load ring, a clamping plate and a pre-load gap between the clamping plate and the casting mold and optionally includes a dimensional compensating ring. When tightened, the clamping plate biases the load ring against the flange thereby distributing a uniform load against the casting mold, compressing the gasket therebetween while narrowing the pre-load gap to accommodate dimensional variations.

An apparatus for transferring molten metal from a melting furnace to a casting furnace is provided. A sensing and control system for the transfer of molten metal from a transfer furnace to a casting furnace is also described. The combination of the transfer apparatus with the sensing and control system provides for the introduction of reduced oxide molten metal into a casting furnace.

Overflow transfer furnace and control system for reduced oxide production in a casting furnace

A molten metal treatment furnace ( ) with metal treatment and level control includes a heating chamber ( ) for containing and heating a supply of molten metal ( ), a pump ( ) connected to the heating chamber ( ), a molten metal treatment chamber ( ) located at the outlet of the pump ( ), and a dosing chamber ( ) located downstream and in fluid communication with the molten metal treatment chamber ( ). A trough ( ) is connected to the dosing chamber ( ) for supplying the molten metal ( ) to a downstream process. A molten metal level sensor ( ) is located in the dosing chamber ( ). The pump ( ) is a variable speed pump having a pump inlet ( ) connected to the heating chamber ( ) and configured to pump the molten metal ( ) through the furnace ( ) during operation. The molten metal level sensor ( ) is connected to the pump ( ) for providing a pump speed control signal to the pump ( ). The molten metal level sensor ( ) is configured to monitor the level of the molten metal ( ) in the dosing chamber ( ) and maintain a preset level of the molten metal ( ) in the dosing chamber ( ) by controlling the speed of the pump ( ) with the pump speed control signal.

The die casting machine includes a trough containing a supply of molten metal and a feed tube extending into the supply of molten metal in the trough. A flow of molten metal is maintained in the trough past the feed tube independent of the transfer of molten metal through the feed tube. The die casting machine further includes a filtering system.
