Abstract:
Device and method for melt treatment of aluminium alloys having excessive inclusions, impurities and unwanted gases to be removed, by (a) cooling the melt at an appropriate cooling rate to a temperature below the liquidus by shearing the melt associated with the introduction of at least one type of inert gases into the melt to form fine bubbles and high shear in the melt, and (b) purifying inclusions in the melt by floating them to the top surface, degassing the undesirable gases by reacting with the inert gas, and forming solid intermetallics containing impurity elements and transferring the melt mixture by the shearing device into a holding furnace, and (c) maintaining the melt in the holding furnace at a temperature below the liquidus and above the solidus temperature to settle the solid intermetallics formed by impurity elements as sediment at the bottom of the holding furnace while flowing the melt with much reduced inclusions, impurities and unwanted gases out of the holding furnace as applicable materials. The method is advantageously applicable for upgrading aluminium alloys from recycled and/or scrapped materials.

Claim (Index 12):
A device for separating impurities from an alloy melt, including:\n (a) a rotor comprising a shaft having a first end and a second end, the shaft having a longitudinal channel with an inlet proximate the first end of the shaft and an outlet proximate the second end of the shaft to allow a fluid to flow into the channel through the inlet, through the shaft and out of the channel at the outlet, (b) a motor to rotate the shaft about its longitudinal axis, and (c) a stator in the form of a sleeve proximate the second end of the shaft, the sleeve having a wall with a plurality of apertures therein, wherein the rotor is encircled by a round stator, whereby in use fluid exiting the longitudinal channel of the shaft is able to pass through said apertures.
