APPARATUS FOR REFINING ALUMINIUM SMELT AND DEVICE FOR DISPERSION SUPPLY OF GAS INTO ALUMINIUM SMELT IN APPARATUS FOR REFINING ALUMINIUM SMELT

摘要

FIELD: aluminium production. SUBSTANCE: in apparatus, on the bottom of refinement chamber, a protrusion is made disposed over rotor of dispersion gas-supply means. In that means, on a part of rotor length from the rotor apex, pockets are made and in remaining narrowed rotor parts, channels for passage of aluminium smelt are available. EFFECT: improved structure. 25 cl, 12 dwg
