<\/p>\nDue to the repeated regeneration of aluminum, the secondary aluminum production process has attracted more and more countries’ attention. With the continuous progress of science and technology, the secondary aluminum industry is developing in the direction of scale, mechanization, automation, specialization, intensification and reduction of environmental pollution.<\/p>\n
<\/p>\n
Actively develop aluminum and aluminum alloy waste pretreatment processes. In the process of processing and manufacturing aluminum and aluminum alloys, in order to improve the performance of the products, the surface of the metal is often treated, sprayed with various coatings, or covered with various organic or inorganic materials. In addition, aluminum and aluminum alloy scrap have a wide range of sources and types, and have been polluted to varying degrees during the process of use, recycling and dismantling, and will be mixed with various non-aluminum materials. These inclusions in aluminum and aluminum alloy scraps will undergo physical and chemical reactions during the smelting process, which will have a greater impact on the quality of secondary aluminum and the environment.<\/p>\n
In order to reduce the impact of inclusions in aluminum and aluminum alloy scraps on the quality and environment of recycled aluminum, it is necessary to actively develop aluminum and aluminum alloy scrap pretreatment processes to eliminate inclusions in aluminum and aluminum alloy scrap before smelting, thereby improving recycled aluminum Quality and reduce environmental pollution.<\/p>\n
Continue to study high-efficiency, energy-saving, and rapid aluminum melting furnaces suitable for processing aluminum and aluminum alloy waste, further energy saving and consumption reduction, improving the efficiency of aluminum melting furnaces, extending furnace life, reducing metal burning losses, and increasing metal recovery rates. With the expansion of scale, the production of recycled aluminum has become more dependent on advanced smelting technology and equipment.<\/p>\n

<\/p>\n
Research on the purification technology of aluminum and aluminum alloy melt to improve the quality of secondary aluminum. The hydrogen content and non-metallic inclusions in aluminum and aluminum alloy melts have an important impact on the quality of secondary aluminum. Therefore, the aluminum and aluminum alloy melts must be purified.<\/p>\n
With the continuous improvement of the quality requirements for secondary aluminum, online degassing is currently the key research direction and development object of major aluminum processing enterprises. At present, the most widely used method is the rotating degassing method<\/a>. The degassing device uses nitrogen or argon as the refining gas, which can effectively remove the hydrogen in the aluminum melt and improve the slag-liquid separation effect. Online melt filtration treatment is the most effective and reliable method to remove non-metallic inclusions in the melt. The best effect is the filter tube, the foam ceramic filter plate<\/a> and the online filtration outside the melt furnace.<\/p>","protected":false},"excerpt":{"rendered":" Due to the repeated regeneration of aluminum, the secondary aluminum production process has attracted more and more countries’ attention.
