Shandong Yuhang Embraces High Speed ​​Rail Times with Multiple Core Technologies

According to the bulk non-ferrous net reprint: Recently, China's high-speed rail transport industry is developing rapidly, and the application prospects of EMU aluminum alloy profiles are promising. Shandong Yuhang alloys rely on strong scientific and technological R&D strength and advanced high-end technologies and equipments at home and abroad, and strive to create high-quality aluminum for EMUs. The profile development platform helps China's high-speed rail industry develop rapidly. It is reported that Shandong Yuhang has now researched and applied for more than ten patents for high-quality aluminum profiles with super-conductivity, high-intensity and other properties, and has been put into production one after another.

China's high-speed rail industry has matured, ranking first in the world in terms of train ownership, type, and operating mileage. Coupled with strong adaptability (construction and operation in extreme weather), short construction period, and low cost, China's high-speed rail industry is deeply affected. Overseas countries favor and have the strength to compete with foreign markets. Aluminum and aluminum alloys have always been valued by China's high-speed rail industry because of their light weight, high strength, corrosion resistance, excellent formability, and high recycling rate. It is understood that, in addition to the CRHI type body is made of stainless steel, the other three kinds of railway passenger train EMUs in China use aluminum alloy material (CRH2, CRH3, CRH5). Taking the calculation of the consumption of 8-9 tons of aluminum profiles and 1.5 tons of aluminum plates for each motor vehicle as an example, the Chinese EMU vehicle body consumes 18,000 tons of aluminum profiles and 30,000 tons of aluminum plates annually. “High-end aluminum alloys are important profiles for China’s high-speed trains. At present, China’s high-speed rail has already gone out of the country and it will undertake high-speed rail projects worldwide. The demand for EMU aluminum will continue to increase,” said a person in the high-speed rail industry.

Shandong Yuhang Special Alloy Equipment Co., Ltd. devoted to building large-scale and high-end aluminum profiles has closely followed the lifeblood of the times, launched conductive rails, buses, and other R&D and production projects for a variety of EMU aluminum alloy profiles. Relying on "a method for manufacturing high-strength and high-conductivity aluminum alloy large-size bars for power equipment", "a method for manufacturing high-strength and high-conductivity aluminum alloy thick-walled pipes for power equipment", and "arranged aluminum such as busbars "Inspection technology for alloys" and many other technical projects, Shandong Yuhang's conductive track, bus bar and other product production technology is near mature and mass production. Its research and development conductive track has high production efficiency, uniform organization, high strength, plasticity and high conductivity, and can be incorporated into national standards. The bus bar also has good electrical conductivity based on excellent performance, and the port is notch flat and the precision of the contact hole is high. There is no hard point at the contact line, which effectively protects the pantograph. The tram is of good flow-receiving quality, which ensures the safety of driving and prolongs the service life of the equipment.

It is understood that Shandong Yuhang has been involved in the high-end aluminum alloy profile industry since 2011. With the help of advanced state-level engineering and technology research centers, world-leading equipment, and high-quality talents, Shandong Yuhang is adept at understanding market dynamics and has mastered the conductive tracks. , Busbars, containers, ultra-high hardness alloy cast rods and other aluminum alloy production and research and development technology, the current market response is good, the industry highly praised.
