  • Method of smelting aluminum
    Patent number: 4007036
    Abstract: Aluminum scrap, dross, and the like is preheated to a temperature of approximately 600.degree. C in a prewarming drum and is then turbulenced in an input funnel leading to a satellite furnace. That turbulencing is effected by feeding the preheated aluminum pieces into a stream of molten aluminum coming from a primary smelting oven and directed tangentially into the input funnel so as thoroughly to turbulence the particles and molten aluminum together. Dross developing in the satellite furnace is compacted and then removed and grouped up for reintroduction to the preheating step so as to extract all of the aluminum therefrom.
