PROCESSO PARA RECUPERACAO DE APARA DE ALUMINIO REVESTIDA DE CALIBRE LEVE |
摘要 |
<p>In a process for recovery of aluminium metal from coated light gauge aluminium scrap the scrap fragments are first decoated and then fed substantially continuously onto the surface of a body of molten metal above a channel-type induction heater. The molten metal is stirred to produce strong down flows at the molten metal surface to submerge the decoated scrap particles. The submergence may be effected by a coreless induction heater acting on the body of molten metal or other electromagnetic device such as one or more linear induction motors which are employed to set up a strong axial down flow at the center of the metal surface or to generate a vortex at that location.</p> |
