Abstract
A method of, and apparatus for, recycling a metal by melting it to remove it from metal-containing scrap through the use of a tiltable, swivel rotary furnace, which is swiveled to a first station for receiving metal-containing scrap, tilted back and rotated while heating to melt the metal, swiveled to a second station where it is stopped and forward tilted to quickly pour off the molten metal into a holding apparatus. The furnace is swiveled to a third station where it is further forward tilted and rotated to discharge the residual scrap, and then leveled and swiveled to the first station while still hot to receive metal-containing scrap, thereby reducing the amount of energy required to reheat the furnace to melting temperature. The furnace comprises a hollow elongated drum having a tapered snout, a door closing the front opening, a power rotary drive to rotate the drum, which is mounted for tilting about a transverse axis, and for swiveling about a vertical axis, and a heater.
