Description
Technical Field
[0001] The utility model relates to the technical field of aluminum smelting, in particular to a hardened aluminum smelting chute. Background Technique
[0002] Aluminum is the most important light metal and is widely used. In industrial production of aluminum, the method mostly adopted is molten salt electrolysis. The raw material is alumina, which is extracted from various aluminum-containing ores. Bauxite is the main raw material for aluminum smelting. The process of aluminum electrolysis is to pass direct current through an electrolyte composed of alumina as the raw material and cryolite as the flux, and decompose alumina in the electrolyte solution at 950-970 °C into aluminum and oxygen. The aluminum liquid deposited on the cathode converges at the bottom of the electrolytic cell, and carbon dioxide and carbon monoxide gases are deposited on the anode. The aluminum liquid is sucked out from the electrolytic cell, purified to remove hydrogen, non-metallic and metallic impurities and clarified, and then cast into various aluminum ingots. During the ingot casting process, the original soft connection of the chute was lined with rock wool. During ingot casting, the rock wool was easy to float up, causing large-area leakage of aluminum liquid, resulting in personnel scalding accidents, with low safety, and it would also damage the equipment. After the aluminum liquid leaked, it was not easy to clean up, and only shutdown treatment could be carried out, reducing production efficiency. Therefore, it is very necessary to design a hardened aluminum smelting chute with strong practicability and high safety. Content of the Utility Model
