摘要： 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.

摘要： Solid scrap metal particles are ingested into molten metal by use of a linear induction motor which establishes a strong upstream in the molten metal adjacent one boundary wall to establish a standing wave at the surface and a corresponding downstream adjacent the opposite boundary, which is preferably in the form of a baffle having a metal outlet passage beneath it. The linear induction motor is conveniently positioned at a sidewell of a melting furnace and a continuous flow of molten metal through the sidewell is established in any convenient way.

摘要翻译：固体废金属颗粒通过使用线性感应电动机吸收到熔融金属中，该线性感应电动机在邻近一个边界壁的熔融金属中形成强大的上游，以在表面建立驻波，以及在相邻边界附近相应的下游，其最好在挡板的形式在其下方具有金属出口通道。线性感应电动机方便地位于熔炉的侧面，并且以任何方便的方式建立了通过侧面室的连续熔融金属流。
