Abstract: 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.
