摘要： A molten metal pump having a base member defining a pumping chamber is provided. The pumping chamber includes an opening in each of a top surface and a bottom surface of the base member. An impeller is disposed in the pumping chamber and is configured to draw molten metal through the opening in the bottom surface and expel the molten metal through an outlet in the base member. A flow diverter is disposed above the opening in the top surface.

摘要： A method for delivering molten metal to a shot sleeve of a casting machine from a molten metal furnace. A molten metal pump is positioned within the furnace. The pump includes a molten metal outlet in fluid communication with the shot sleeve. A shaft and impeller or screw assembly of the pump is selectively rotated to introduce molten metal to the shot sleeve in a predetermined quantity. The predetermined quantity is determined by a controller that receives a signal from a trigger mechanism associated with the molten metal outlet.

摘要： A method of fluxing or degassing a molten metal residing as a bath in a furnace. The bath of molten metal includes a bath surface height and the method provides at least one rotating impeller in the molten metal bath to initiate a flow of the molten metal. The flow in the molten metal results in elevating a portion of the molten metal above the bath surface height where at least one of a fluxing agent and an inert gas is introduced into the elevated portion of the molten metal.
