Abstract:
The present invention relates to a system for melting aluminum and recycling black dross, including an aluminum melting furnace responsible for melting aluminum scraps in molten aluminum and a black dross recycling device responsible for recycling black dross generated when the aluminum scraps are melted in the molten aluminum.The aluminum melting furnace includes a heating chamber provided with heating units responsible for heating the molten aluminum; and a melting chamber provided with an eddy unit responsible for generating an eddy descending in a spiral in the molten aluminum, a flux supply unit responsible for adding a flux to the eddy, and a raw material supply unit responsible for adding the aluminum scraps to the eddy, wherein, in the eddy unit, black dross formed when inclusions contained in the molten aluminum are captured by the flux is repeatedly descended and floated in the molten aluminum through the eddy, so that the black dross is collected into a spherical shape to form spherical black dross, and the black dross recycling device is responsible for recycling the spherical black dross.
