Aluminum plate production method with low energy consumption

Abstract

The invention discloses an aluminum plate production method with low energy consumption. High-temperature electrolytic aluminum melt is fed into a smelting furnace directly, the process of casting electrolytic primary aluminum melt into aluminum ingots for remelting and remelting heating are omitted, labor is saved, the energy consumption of aluminum plate production is reduced greatly, the production cost is reduced, and the production benefit is increased; meanwhile, aluminum burning loss during remelting is reduced, and the economic benefit is increased; and the aluminum melt is refined by adding carbon tetrachloride, grains are refined by adding an aluminum-titanium alloy, the problems of many oxidation impurities and high hydrogen content of the electrolytic aluminum melt are solved, and the product quality is improved and meets production standards.

Description

technical field [0001] The invention belongs to the technical field of aluminum plate production, and relates to an aluminum plate production method, in particular to a low energy consumption aluminum plate production method. Background technique [0002] Under the situation of advocating low-carbon economy in the world, "energy saving and emission reduction" has become the review point for the current family to strengthen macro-control. The non-ferrous metal industry is one of the six major energy-consuming industries. The energy consumption of the non-ferrous metal industry is mainly concentrated In the three major fields of mining, smelting and processing. Among them, the total energy consumption of electrolytic aluminum is the largest in smelting energy consumption. Although the energy consumption of the aluminum processing industry to produce 1 ton of aluminum sheet is 1 / 18 to 1 / 23 of the average energy consumption of the production of 1 ton of primary aluminum, which ...
