Document Type and Number:
WIPO Patent Application WO/2007/091386
Kind Code:
A1
Abstract:
[PROBLEMS] To feed molten metal to the outside of a container at an appropriate flow speed. [MEANS FOR SOLVING PROBLEMS] The device has an air hose connectable to a gas passage; a pressurized gas feeding part for feeding a pressurized gas to the container through the air hose and the gas passage; a measurement part for measuring the flow speed of the molten metal fed from the inside to the outside of the container through a flow passage and piping, the feeding of the molten metal being made by the pressurized gas flowing into the container through the air hose; and a control part for controlling the pressure value of the pressurized gas that is fed to the container, the control of the pressure value being performed such that the flow speed measured by the measurement part is set to a predetermined value.
