Description

Feeding device of aluminum smelting furnace

Technical Field

The utility model relates to a metal melting technical field, concretely relates to aluminum smelting furnace.

Background

Aluminum is a silver-white metal and is present in the earth's crust second only to oxygen and silicon in the third place. Aluminum has a relatively low density of only 34.61% of iron and 30.33% of copper, and is therefore also referred to as a light metal. Aluminum is a nonferrous metal second to steel in both yield and usage in the world. The density of aluminum is only 2.7103g/cm3, which is about 1/3 times the density of steel, copper or brass. Because of the light weight of aluminum, aluminum is often used for manufacturing land, sea and air vehicles such as automobiles, trains, subways, ships, airplanes, rockets, airships and the like so as to reduce the self weight and increase the loading capacity.

The raw material in our daily industry is called aluminum ingot, which is called 'remelting aluminum ingot' according to the national standard (GB/T1196-. It is produced by electrolysis of alumina-cryolite. There are two main categories of aluminum ingots entering industrial applications: cast aluminum alloys and wrought aluminum alloys. Cast aluminum and aluminum alloys are cast by producing aluminum castings by a casting method; wrought aluminium and aluminium alloys are processed products of aluminium produced by pressure processing methods: plates, strips, foils, tubes, rods, profiles, wires, and forgings. According to the national standard, the aluminum ingots for remelting are divided into 8 marks according to chemical components, namely Al99.90, Al99.85, Al99.70, Al99.60, Al99.50, Al99.00, Al99.7E and Al99.6E (the number after the Al is noted is the aluminum content). The so-called "A00" aluminum, which is actually aluminum containing 99.7% purity, is marketed in London as "Standard aluminum". It is known that the technical standard of China is from the former Soviet Union in the fifties, "A00" is a Russian brand in the national standard of Soviet Union, "A" is a Russian letter, not an English "A" character, not an "A" of a Chinese phonetic alphabet and an international connection, and is called "standard aluminum" rather exactly. The standard aluminum is an aluminum ingot containing 99.7% aluminum, which is registered in the london market.
