On July 20, the first set of high-speed maglev transportation system with a design speed of 600 kilometers per hour was successfully launched in Qingdao, China. Its successful development is of great and far-reaching significance for building a new engine of China's equipment industry, forming a new advantage in rail transit, and seizing the commanding heights of scientific and technological competition. It is of great and far-reaching significance to speed up the construction of a modern comprehensive three-dimensional transportation network and support the strategy of "science and technology power" and "traffic power". Nanshan Aluminum Co., Ltd. provides existing car profiles, technological breakthroughs and innovation, contribute to the rise of China, and achieve the glory and dream of the national aluminum industry.

High-speed maglev transportation system is a key project of rail transit in the 13th five-year Plan of the Ministry of Science and Technology. The high-speed maglev train with a speed of 600km / h has more stringent requirements for aluminum profiles during the high speed. Nanshan Aluminum Industry has participated in the development of aluminum alloy profiles for this project by CRRC Qingdao Sifang (601126) Co., Ltd. since 2018, there are special requirements in microstructure, tensile properties, fatigue properties, exfoliation corrosion properties, stress corrosion properties and weldability of 6A01, 6005A, 6106 and 6082 aluminum alloys for the project.

Nanshan Aluminum Industry participated in the research and development of extrusion parts for high-speed maglev suspension frame and prototype car body profile for 600 km / h high-speed maglev train-prototype car compartment and sandwich profile development. a total of dozens of cross-sections are mostly profiles with large cross-section, multi-cavity and large wall thickness deviation. Through the research on alloy composition optimization and control technology, scrap alloy ingot melting and casting technology, casting homogenization technology, numerical simulation aided extrusion die design and processing technology of 6 series aluminum alloy materials for rail transit car body, Nanshan Aluminum Industry has broken through a number of key technologies, solved a large number of technical problems, and mastered the core technology of special-shaped cross-section aluminum alloy profile extrusion. At the same time, it has and mastered the batch production capacity of aluminum alloy profiles for car body under industrial conditions.

The ability of independent innovation is the key to the success of the company's development. Nanshan Aluminum Company seizes the opportunity of promoting supply-side structural reform and the transformation of new and old kinetic energy to speed up the transformation and upgrading of industrial structure. Committed to automotive, rail transit, aviation profiles and other manufacturing fields. Relying on the advantages of the complete industrial chain, existing enterprise technology centers, academician workstations, postdoctoral workstations and other scientific research and development platforms, as well as the "Aluminum Alloy pressure processing Engineering and Technology Research Center" of the domestic aluminum processing industry, actively promote evolution, intelligence, lightweight upgrading, with thoughtful service, excellent performance-to-price ratio, stable quality, accurate solution, To provide customers and friends with appropriate and accurate product solutions.

In the future, in the face of the new situation, new opportunities and new challenges, Nanshan Aluminum will always adhere to the development strategy of "innovation-driven, manufacturing and intensive processing". Based on scientific and technological innovation, strengthen foundation consolidation, strengthen breakthroughs, strengthen innovation drive, strengthen extended value-added, strengthen green development, strengthen overseas cooperation, with the help of the industrial chain advantages of "one-stop" solutions, unswervingly implement the concept of "green environmental protection and sustainable development" is committed to making new and greater contributions to the development of enterprises and promoting local economic development.
