DEVICE FOR REFINING MELT OF METALS OR ALLOYS Russian patent published in 2004 - IPC

Abstract RU 2228379 C1

FIELD: metallurgy; devices for refining melt of aluminum and its alloys. SUBSTANCE: proposed device includes routes and nozzles for delivery of inert and active gases which are located independently. Part of inert gas delivery route immersed in melt is made in form of coil. Inert gas nozzles are smoothly located over circumference. Number of nozzles ranges from 2 to 6. Diameter of outlet openings of inert gas nozzles ranges from 0.3 to1.5 mm and diameter of active gas nozzles ranges from 2 to 8 mm. Coil ensures heating of inert gas to high temperature. Location of nozzles ensures spraying of active gas flow in finest bubbles. EFFECT: enhanced efficiency of refining process; simplified construction; low cost of device. 3 cl, 1 dwg
