Description

Technical Field

[0001] The utility model relates to the technical field of melting furnaces, in particular to a metal aluminum melting furnace. Background Art

[0002] Aluminum alloy is based on pure aluminum and other chemical elements are added, such as iron, silicon, magnesium and other elements, to make its strength higher, ductility better, easy to form, with good surface gloss, making its products very beautiful. In order to achieve these, we must turn pure aluminum into aluminum alloy, which requires melting pure aluminum into liquid aluminum, and then adding other chemical elements to it, allowing their atoms to recombine to form a new atomic spatial structure, making the interaction force between chemical bonds stronger and more stable.

[0003] Chinese Patent with publication number CN113465376A discloses an aluminum liquid melting furnace for casting, including a furnace body, a furnace cover, a hanging plate, a cylinder, a feeding bin, a smoke exhaust pipe, a furnace cavity, heating rods, a crucible and a smoke exhaust port. The furnace cover is movably installed at the center of the upper end of the furnace body. The hanging plate is fixedly installed at the upper end of the furnace cover. The cylinder is fixedly installed at the upper left part of the furnace body, and the upper end of the cylinder is fixedly connected with the lower left end of the hanging plate. The feeding bin is fixedly installed at the upper right end of the hanging plate, and the feeding bin penetrates through the hanging plate and the furnace cover and is connected to the furnace body. The smoke exhaust pipe is fixedly installed at the upper right part of the furnace body. The furnace cavity is opened at the center of the interior of the furnace body. This aluminum liquid melting furnace for casting can effectively reduce the adhesion between the crucible and the heating rods, and can remove manganese impurities in the aluminum liquid, improving the purity of the aluminum liquid.
