ALUMINUM REFINING APPARATUS AND ALUMINUM REFINING METHOD

WIPO Patent Application WO/2013/168214

A1

The present invention addresses the problem of providing an aluminum refining apparatus that enables a reduction in refining time and an increase in yield. This aluminum refining apparatus (1) is provided with: a vessel (10) with a bottom that accommodates molten raw aluminum; a heating means (20) for heating the vessel (10); a cooling means (30) for cooling part of the vessel (10); and a primary crystal detaching means (40) for detaching primary crystal particles (PAl) that have crystallized on the inner surface of the vessel (10). The aluminum refining apparatus (1) is characterized in that: the cooling means (30) has a gas flow passage (3a) disposed in such a manner as to surround the vessel; and the gas flow passage (3a) is partitioned into a plurality of divided passages aligned in the vertical direction, and the direction of flow of a cooling gas reverses in the odd-numbered stages of the divided passages from the top, and the even-numbered stages of the divided passages from the top.
