System for melting aluminum and recycling black dross and methods of melting aluminum and recycling black dross

摘要

The present invention relates to a system for melting aluminum and recycling black dross which has an aluminum smelting furnace for melting aluminum parts into molten aluminum, and a black dross recycling device for recycling black dross generated when the aluminum parts are added The molten aluminum furnace has a heating chamber provided with heating units for heating the molten aluminum; and a melting chamber provided with a vortex unit for generating a vortex which spirally sinks in the molten aluminum, a flux supply unit for introducing a flux into the vortex, and a raw material supply unit for introducing the aluminum parts into the vortex, wherein, in the vortex unit, black scabies formed when inclusions contained in the molten aluminum are bound by the flux through which the swirl repeatedly sinks and rises in the molten aluminum, so that the black dross accumulates into a spherical shape to form a dome to form spherical black dross, and the black dross recycling device serves to recycle the spherical black dross.
