Description

Technical Field

[0001] The invention relates to a secondary aluminum technology, in particular to a fully automatic slag removal device for a secondary aluminum smelting furnace. Background Art

[0002] Recycled aluminum is also called "secondary aluminum". It is aluminum obtained by smelting scrap aluminum parts and scrap aluminum materials. The smelting of recycled aluminum began at the beginning of this century and developed greatly during and after World War II. Now the annual output of recycled aluminum in the world is about 4 million tons, which is equivalent to about 25% of the original aluminum output. In some industrially developed countries, such as the United Kingdom, Italy, France, and the United States, recycled aluminum has become an important source of supply for aluminum and aluminum alloys, accounting for a considerable proportion of the original aluminum output. Because the increase in the output of original aluminum has led to the increase in the amount of scrap aluminum parts and scrap aluminum materials, modern technology has made the quality of recycled aluminum no less than that of the original aluminum alloy with the same composition, and each ton of recycled aluminum has a high yield and a high yield. The energy consumption of aluminum is only about 5% of that of producing original aluminum from ore. The production cost is low and the investment is small. The main raw materials for smelting recycled aluminum are industrial depreciated scrap aluminum parts (such as aircraft scrap parts and engines, casing covers, etc.) and scrap aluminum materials generated in the aluminum processing process (including plates, pipes, bars, profiles, debris, foils, etc.). Before smelting scrap aluminum, various scrap aluminum parts need to be sorted or disintegrated (cut into regular small blocks) to separate iron and other non-ferrous metal parts, and then properly formulated and processed to achieve the required recycled aluminum and aluminum alloy composition. During production, a large amount of aluminum slag will be left after smelting.
