Problems solved by technology
However, aluminum compressed pellets will contain multiple voids during the process of compressing aluminum flakes
Therefore, there is a problem in the existing aluminum melting furnace that since heat cannot be transferred to the central portion of the compressed aluminum pellets thrown into the molten aluminum, the melting efficiency decreases, and the compressed pellets of aluminum float to the surface of the molten aluminum and Contact with the atmosphere, thus forming oxides
Thereby, the existing problems of the existing aluminum melting furnace are that even if the aluminum compressed pellets are put into the aluminum melt pumped by the melt stirring chamber, the melting efficiency is still reduced, and the generation of aluminum oxide is large, so that the pure aluminum Melting recovery rate drops
Therefore, when the problem existing in the existing aluminum melting furnace, even if the flux treatment is carried out, the melting recovery rate of pure aluminum will still decrease

Abstract
An aluminum melting furnace, according to the present invention, comprises: a heating chamber that includes a heating unit for heating molten aluminum; and a melting chamber that includes a vortex unit that generates a vortex that moves down to the molten metal while swirling, a flux supply unit that introduces a flux into the vortex, and a raw-material supply unit that introduces aluminum scraps into the vortex. According to the present invention, spherical black dross is formed by aggregating black dross, which a flux generates by selectively trapping non-metal inclusions, in a spherical form through the vortex, thereby making it possible to reduce the amount of aluminum metal included in the black dross. In addition, it is possible to reduce the cost required for reprocessing dross since a separate dross reprocessing process for retrieving the aluminum contained in the dross is not necessary.
Description
technical field [0001] The invention relates to an aluminum melting furnace capable of melting aluminum scrap. [0002] This application claims priority rights based on Korean Patent Application No. 10-2015-00 29943 filed on March 3, 2015, and the entire contents disclosed in the Korean Patent Application are incorporated herein as a part of this specification. Background technique [0003] Many aluminum parts used in automobiles, home appliances, construction materials, etc. are manufactured using aluminum casting equipment. The aluminum melting furnace supplies molten aluminum to this aluminum casting device. An aluminum melting furnace is a device that uses high heat to melt and shape aluminum scraps of a specified size. [0004] The existing aluminum smelting furnace includes a burner heating chamber for heating molten aluminum, a melt stirring chamber equipped with a melt pump for pumping the aluminum melt discharged from the heating chamber, and an The molten metal ...
