What is the main recycling method of aluminum waste

In our lives, aluminum alloy is also a relatively common metal material, especially in the door and window industry and hardware accessories industry, a large number of aluminum alloy products are sold every year. But many consumers buy aluminum products back, after a long time, naturally there will be some problems, such as rust, at this time many people will choose to replace it. In this case, the aluminum alloy becomes a waste product, and most people will choose to throw it away. In fact, aluminum alloy can be sold, today, Xiaobian to tell you, what is the method of recycling aluminum waste, and how much money to recycle.

The price of aluminum scrap is not high now. At the current price of aluminum ingots, because the price of scrap aluminum is also changed according to the price of aluminum ingots. So, what is the recycling method of aluminum alloy waste?

1, waste aluminum recycling treatment method: the intention of the pre-disposal of waste aluminum is to remove other metals and impurities in the waste aluminum, the second is to classify the waste aluminum according to the composition, so that the alloy composition is used to a large extent, and the third is to dispose of the oil, oxide and paint on the surface of waste aluminum. The result of the end of the pre-disposal is to dispose the waste aluminum into the furnace condition, and the fourth is to make the aluminum (containing alumina) of the aluminum containing waste be the most economical and reasonable use.

2, the domestic waste aluminum pre-disposal skills are still very simple and backward, even in large recycled aluminum plants, the pre-disposal of waste aluminum is not more advanced skills. As far as the recycling and use disposal methods of single type of waste aluminum are concerned, waste aluminum that is single or does not contain other impurities is usually not pre-disposed of clutter, and is only classified according to the type and composition of waste and piled up alone. A single type of waste aluminum in use only need to check a component of the test, you can know the composition of the batch, is an excellent recycled aluminum material, usually do not need to make any pre-disposal can be put into the furnace smelting, in the smelting of a certain aluminum alloy, can choose the corresponding composition and type of waste aluminum directly participate in the reverberatory furnace smelting, and can be easily smelted into the corresponding trademark aluminum alloy.

Some waste aluminum with high copper and zinc content can also be used as the center alloy for adjusting the composition of aluminum alloy in the smelting process. In the selection of small reverberatory furnace or crucible furnace enterprises, it is necessary to crush the large volume of waste aluminum (shear or other methods) into the material speed that meets the furnace standard. It is worth mentioning that some single kinds of scrap aluminum will mechanically contain a small number of non-aluminum metals, such as scrap steel pieces such as screws on scrap aluminum doors and Windows, although the content is small, it will seriously affect the quality of the alloy, so it must be separated before melting.

3, waste aluminum recycling heavy medium beneficiation method: that is, the use of heavy medium heavy separation method to separate the density of copper and other heavy non-ferrous metals greater than aluminum, which uses the density of aluminum is smaller than other heavy non-ferrous metals principle, so that waste aluminum floating in the medium above, while heavy non-ferrous metals sink at the bottom, to achieve the purpose of separation. But the key to the technology is to screen for a medium that is denser than aluminum and less dense than copper, which is by no means water or other liquid, certainly a fluid. When working, the fluid is in reciprocating motion, and the waste aluminum is separated by floating on the medium.

The above is a small series for everyone to share some relevant knowledge about waste aluminum, I hope to help you. In fact, if the aluminum alloy is really recycled, the price is really not high, and the price in different regions is also different. So when we sell, we still need to go to the local market to understand more, so that we can know how much our own waste aluminum can sell. Waste aluminum alloy re-aluminum alloy processing, for consumers, manufacturers have profits, but also can reduce the phenomenon of aluminum alloy discarded at will, better protect our natural environment.
