Recycled Aluminum Processing Production Technology And Development Direction

The reuse of resources is an important means of building an "environmentally friendly, green" production and lifestyle. Metal resource aluminum recycling is an important manifestation of the application of this new method to production and life. Based on the current development status of the secondary aluminum processing industry, the application level of production technology and the future development direction, a simple analysis is made to provide theoretical support for improving the application of metal smelting technology and metal utilization rate, and to improve my country's energy utilization rate.

The production investment of the secondary aluminum m-r industry is small and the scale is small

Currently in the primary stage of social socialism, there are certain restrictions on the application and innovation of production technology in various industries. On the one hand, the vast land and resources and abundant metal mines have resulted in a weak sense of the concept of saving and reusing metal resources, and people have a low degree of development of recycling technology. On the other hand, due to the late start of the application of metal recycling technology, the current The production scale of metal recycling processing in China is restricted by technology and market demand. The production investment in the secondary aluminum processing industry is low, which makes the secondary aluminum processing industry smaller in production scale.

There are shackles in the production technology of the secondary aluminum processing industry

At present, the application level of domestic secondary aluminum Dn_m_ production technology is relatively low. The domestic secondary aluminum production technology still stays at the level of traditional "indigenous" smelting and metal casting technology. It is the thermal efficiency and recycling rate of metal aluminum in the recycling process. ...The degree is low, which affects the production and use of recycled aluminum. In addition, with the gradual increase in the application scope of metal aluminum in China, the scale of the recycling amount of recycled aluminum is gradually increasing. As these aluminum cannot be recycled in time, a large amount of metal resources are wasted and the resources are endangered. development of.

The development of raw materials for domestic secondary aluminum processing is low

The technical application of secondary aluminum mainly comes from the application of advanced foreign smelting and recycling technologies. On the one hand, people lack the awareness of domestic metal smelting and recycling, and on the other hand, the development of raw materials for domestic aluminum product recycling is relatively low. The raw material source table for recycled aluminum processing and production in the past five years shows: 2011-20 15 years The raw material sources of secondary aluminum are mainly foreign, and the domestic proportion is relatively low.

The backward production technology of recycled aluminum causes serious environmental pollution

There are certain production constraints in the production technology of secondary aluminum, resulting in slower production progress of secondary aluminum and low production efficiency. During the production of secondary aluminum, a large amount of coal is required as a power guarantee for secondary aluminum smelting, which causes air pollution due to coal combustion; On the one hand, the traditional secondary aluminum processing process has a low recycling rate of waste raw materials. A large amount of waste metal aluminum is generated during the aluminum smelting and regeneration process, which will also cause environmental pollution.

Processing and production technology of recycled aluminum

Application of secondary aluminum recycling smelting technology

With the gradual update and development of scientific and technological means, secondary aluminum recycling smelting technology is gradually applied to secondary aluminum smelting technology. At present, the more common smelting technology equipment is the two-stone melting furnace and the side shaft melting furnace. The main work of the two smelting technologies The principle can be summarized as follows: firstly spray a quantitative alloy smelting into the waste metal, use the principle of decomposition pressure to divide the pressure treatment of the waste metal, and then use electromagnetic stirring and vacuum separation technology to melt the waste metal. This advanced secondary aluminum processing technology increases the types of metal capacity and the capacity range. At the same time, the advanced smelting technology mainly uses multiple physical principles to fully dissolve the metal, and the degree of pollution produced is lower than that of the traditional smelting technology. Many, reduce the pollution degree of recycled aluminum processing to the environment.

Application of secondary aluminum recycling casting technology

The improvement of secondary aluminum processing and production technology is also reflected in the application of secondary aluminum casting technology. The application of advanced production technology has also opened up a new development direction for the casting of secondary aluminum, mainly including metal casting, pressure casting, low pressure casting and other casting forms. Relying on computer means to provide electronic models for secondary aluminum casting, and perform the division of labor between small parts production and large-scale main casting in the secondary aluminum casting production process. In the production and casting process of secondary aluminum, through the analysis of the electronic data in the early stage of production, the secondary aluminum is cast in different ways to improve the scientific utilization rate of secondary aluminum and promote the gradual development of the secondary aluminum industry.

Application of secondary aluminum waste treatment technology

A certain amount of waste is generated in the production process of secondary aluminum. Since the smelting and casting of metal aluminum in the recycling of waste metal aluminum usually mainly uses physical means to re-use metal aluminum, most of these wastes are in the smelting process. It becomes a kind of energy that is incorporated into the gas produced after smelting, and the other part needs to be consumed by secondary physical applications. This new type of waste treatment technology improves the utilization rate of raw materials and reduces the environmental pollution of recycled aluminum production and processing.

The future development prospects of secondary aluminum processing

With the gradual improvement of the level of science and technology, the scope of application of recycled aluminum has gradually expanded. On the one hand, it has increased the utilization rate of metals and opened up new directions for the rational use of metals. It has provided effective solutions to solve the energy shortage in economic development and is leading the development of the metal industry. New power, on the other hand, the continuous innovation of recycled aluminum technology to create new metal products.

Conclusion

Analyzing the processing and production technical means and future development prospects of secondary aluminum is a powerful way to improve China’s energy development, helping to solve the current problems in secondary aluminum processing, promoting the comprehensive utilization of metal resources, and strengthening the development and research of new energy It is a shortcut to realize an "energy-saving and environmentally friendly" country and promote the rationalization of the economic development structure.
