摘要： A dosing chamber is insertable within and removable from the metal holding chamber of a molten metal furnace and is not formed as an integral part of the refractory lining of the molten metal furnace. The dosing chamber includes a chamber shell having a gas inlet port and a molten metal discharge port. The gas inlet port is functionally adapted to sealingly receive a gas stopper tube within the port. With a pressurized inert gas introduced through the gas stopper tube, molten metal contained within the dosing chamber is force out of the discharge port and up and into a metal receiver. The dosing chamber method and apparatus of the present invention is functionally adapted to be insertable within a variety of commercially available furnaces. The dosing chamber method and apparatus of the present invention may also be functionally adapted to be readily removable from the molten metal chamber such that the dosing chamber can be removed and cleaned as such is desired or required.
