Title:
金属処理および液面レベル制御を備えた溶融金属配湯炉
Document Type and Number:
Japanese Patent JP4731810
Kind Code:
B2
Abstract:
A dosing furnace (10) with metal treatment and level control includes a holding chamber (12) for containing a supply of molten metal (50), a pump (22) connected to the holding chamber (12), a molten metal treatment chamber (16, 18) located at an outlet (26) of the pump (22), and a dosing chamber (40) located downstream and in fluid communication with the molten metal treatment chamber (16, 18). A molten metal level sensor (56) is located in the dosing chamber (40). The pump (22) is a variable speed pump having a pump inlet (24) connected to the holding chamber (12) and configured to pump the molten metal (50) through the dosing furnace (10) during operation. The molten metal level sensor (56) is connected to the pump (22) for providing a pump speed control signal to the pump (22). The molten metal level sensor (56) is configured to monitor the level of the molten metal (50) in the dosing chamber (40) and maintain a preset level of the molten metal (50) in the dosing chamber (40) by controlling the speed of the pump (22) with the pump speed control signal.
