Document Type and Number:
Japanese Patent JP3357974
Kind Code:
B2
Abstract:
A method that may be used for transferring molten metal by using pressurized gas, molten metal in a metal furnace (1) is automatically sucked into a molten metal chamber (2) installed within the metal furnace through a fluid suction pipe (4) by a balanced pressure inside the chamber. Then, when the molten metal sucked into said chamber is transferred to a specified position through a fluid feed pipe (3) by applying a pressurized gas from the upper part of said chamber, the flow rate of the molten metal at the junction part between the fluid suction pipe (4) and feed pipe (3) or at the opposed part of an open end of the fluid suction pipe against that of the fluid feed pipe is accelerated, becoming a higher flow rate at other parts of the fluid feed pipe. A molten metal transfer apparatus (15) characterized in that the tightly closed upper part of a molten metal chamber (17), installed in a metal furnace, is connected with an inlet/outlet pipe (20) of pressurized gas and the lower part of said chamber is connected with the base part of a fluid feed pipe (18). In the neighborhood of the base part of said fluid feed pipe (18), a fluid suction pipe (19) is connected, and the another end is opened at the lower part of the metal furnace (1), and the cross-sectional area of the fluid feed pipe (18) at the junction part between said suction pipe (19) and feed pipe (18) is contracted to be smaller than that at other parts of the feed pipe.
