The processing method of scrap aluminum ingots tempered
Scrap material was prepared firstly, primary classification, classification of scrap pile, such as aluminum, deformation, Aluminum Alloy casting Aluminum Alloy mixture, etc.. For aluminum products, should be dismantling, removal and connection of steel aluminum and other nonferrous metals, after cleaning, crushing, magnetic separation, stoving scrap material. For thin and loose pieces of waste aluminum parts, such as locking arms, speed gears, bushings and aluminum scraps, we should use hydraulic metal baler to pack them. For steel cored aluminium strand, the steel core should be separated first, then the aluminum wire is wound into coils.
Liquefaction separation is the development direction of scrap metal recycling of aluminum in the future, it will scrap miscellaneous pretreatment material and re casting combination, not only shorten the process, but also can avoid the maximum air pollution, but also makes the metal net recovery rate is greatly improved.
There is a gas particle filter by allowing the device, in the liquefied layer, aluminum deposited on the bottom in the attachment of the scrap paint of organic matter at 450 DEG is decomposed into gas, tar and solid carbon, through internal combustion oxidation separator. The waste material is stirred by a rotating drum, mixed with the dissolved liquid in the storehouse, and impurities such as sand and gravel are separated into the sand and gravel separation zone, and the dissolved and discharged passes are returned to the liquefied storehouse through the recovery propeller.
