Title:
METHOD AND DEVICE FOR TAKING OUT MOLTEN METAL
Document Type and Number:
Japanese Patent JP3421856
Kind Code:
B2
Abstract:

PURPOSE: To safely and surely take out molten metal without using a mechanical means and also bringing the molten metal into contact with the air by applying the reducing pressure and the pressurization with inert gas to the molten metal surface through a pipe passage and controlling the molten metal.
CONSTITUTION: A vertical pipe 3a is connected to the upper part of one side 2a of a vertical U-shape pipe 2 through a horizontal pipe 3b in a suction pipe 3, and the tip part of the pipe 3a is inserted into the molten metal. One end of a molten metal feeding pipe 4 is connected to the lower part of the other side 2b in the U-shape pipe 2 and respective supplying and exhausting pipes 5, 6 for insoluble gas are connected to the opening side of the U-shape pipe 2. On the way of pipes connecting the respective supplying and exhausting pipes 5, 6 to a gas supplying pump and a gas exhausting pump, solenoid valves are respectively arranged and by operating the solenoid valve, the pressure is controlled. By reducing the pressure on the molten metal surface in the pipe 2a, the molten metal is allowed to flow toward the arrow marks 11, 12, 13, 14 and supplied to the necessary position through a molten metal feeding pipe 4 according to the arrow mark 15.
