Title:
MOLTEN METAL PROCESSING DEVICE AND MOLTEN METAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/099285
Kind Code:
A1
Abstract:
A molten metal processing device according to the present invention comprises a refining agent feeder: provided so as to penetrate the side wall of a container in the diameter direction of the container; provided so as to be positioned higher than the bath surface height of molten metal before an impeller is immersed in the molten metal in the container and lower than the bath surface height of the uppermost part of the molten metal when the impeller is immersed and rotates in the molten metal in the container; and having a nozzle for blowing, into the container, a refining agent for refining the molten metal. Therefore, according to an embodiment of the present invention, refining efficiency is improved in comparison to when the refining agent is fed from the upper side of a container as in a conventional method, thereby enabling use of the refining agent and refining time to be reduced.
