METHOD FOR FILTERING MOLTEN METAL AND METHOD FOR POURING MOLTEN METAL USING THE SAME, AND MOLTEN METAL POURING APPARATUS USING THESE METHODS
Document Type and Number:
Japanese Patent JP2009072808
Kind Code:
A
Abstract:

To provide a molten metal pouring apparatus etc. which can sufficiently filter molten metal by enabling the molten metal to pass through a filter with a small mesh size.

The molten metal pouring apparatus 1 is equipped with: a pressurization means 6 pressurizing molten metal M stored in a sealed crucible 4; a leading out pipe 25 introducing the molten metal pressurized by the pressurization means to the outside of the crucible; a ladle 26 temporarily storing the molten metal made to flow-in from the leading out pipe; and a molten metal filtration filter 27 provided in the vicinity of the inflow port 26a of the ladle and filtering the molten metal made to flow from the leading out pipe into the ladle. By employing the constitution where the molten metal is passed through the filter to be filtered while being pressurized by the pressurization means, even if a filter with a fine mesh is used, there is no risk of clogging, and the filter with the finer mesh can be used.
