As soon as you walk into the office building of Jinxi Axle, the company's development history is displayed in the window. The axle, a seemingly simple product, has gone through decades of development and innovation, and has made a significant contribution to the development of China's railway industry.

At the beginning of the reform and opening up, in order to adapt to the booming development of railway transportation at that time, the state selected axle manufacturers across the country. With the equipment advantages of the 340-ton precision forging machine and advanced production technology, Jinxi was identified as one of the domestic railway axle manufacturers. one. In 1979, the first axle forged in Shanxi came off the production line, breaking my country's long-term dependence on imported railway axles.

"Axles have always been the core product of the company. At present, one of our most important products is the axle of the 350-kilometer high-speed EMU used in the entire train." Kang Feng, deputy general manager of Jinxi Axle in charge of product research and development, said.

At 8:00 on January 1 this year, the G84 Fuxing EMU train bound for Beijing from Changsha left Changsha South Railway Station and headed to Beijing West Railway Station along Wuhan to Zhengzhou. The entire train is equipped with 350-kilometer high-speed EMU axles produced by Jinxi Axle, marking another key step in the process of localization of high-speed rail axles in my country.

Kang Feng told reporters that behind the localization of high-speed EMU axles is the innovation and persistence of Jinxi Axle for more than ten years. Since 2007, Jinxi Axle has carried out key technology research and product trial production of EMU axles, mastered the key core technologies of the entire process of high-speed rail axles from manufacturing to testing, and developed products that meet my country's EMU axle technical standards. , its main properties such as strength, impact toughness, and metallographic structure are superior to imported products. In 2015, the high-speed rail axles produced in Shanxi were installed on my country's first two 350 kilometers per hour Chinese standard EMUs and completed the 600,000-kilometer operation assessment; in 2017, the Shanxi high-speed rail axles passed the CRCC certification and became the first batch in China to have this One of the two companies with the qualification; in 2022, it will be installed on two new Fuxing Hao comprehensive inspection vehicles; in 2023, the Shanxi Axle 350-kilometer high-speed EMU axle will be fully installed on four new Fuxing Hao EMUs; At the beginning of 2024, the 350-kilometer high-speed EMU axle in Shanxi will enter the stage of full train installation and passenger use.

While talking, Kang Feng led reporters to the precision forging workshop. Here, the huge 700T precision forging machine production line is working in an orderly manner. The steel billet weighing hundreds of kilograms is burned red through the annular heating furnace. Under the continuous stamping of the precision forging machine, the steel billet is forged into the shape of an axle. After cooling, it waits to enter the next process. The worker who operates the machine said that this precision forging machine can forge a steel billet in 6 minutes and can produce about 400 finished axles every day.

It is understood that Jinxi Axle has an annual production capacity of 100,000 axles. In 2023, its market share in the China Railway Group's railway freight train axle joint procurement project will be approximately 33%, occupying an important share of domestic axle production. .

As a representative of high-end equipment manufacturing, rail transit equipment is gradually developing towards high quality, intelligent, green and diversified. "Over the years, the company has successfully developed a series of advanced axle technologies with independent intellectual property rights by continuously introducing high-tech and strengthening investment in technology research and development." Pointing to a finished axle, Kang Feng said, "We have made progress in intelligence. Through in-depth exploration and innovation, we introduced sensors and data acquisition technology to realize real-time monitoring and analysis of key parameters such as wheel drag force, temperature, and rotational speed, which greatly improved the operating efficiency and safety of the axle.”

Thanks to the good quality and technological attributes of the products, in terms of main railway products, Shanxi has achieved remarkable results in developing the axle market in the past two years, maintaining a stable and progressive development trend, continuing to consolidate its domestic industry position, and internationalizing its business scale Continued growth.

Implement a new round of large-scale equipment updates and do a good job in demand traction and technology promotion

"This is a C70E general-purpose gondola, which is mainly used to transport coal, ore, steel, wood and other goods. Last year, the company took more than 4 months to complete the production and delivery of 1,150 units of this model, setting a high production record of 410 units in a single month."

"This is a GQ70 light oil tanker that can transport gasoline, kerosene, diesel and other chemical media. In November last year, the company successfully won the bid for 400 GQ70 light oil tankers from China Railway Materials Co., Ltd., becoming the largest deal in the past five years. Tanker orders.”

In the company's product display area, Li Honglin introduced Jinxi Axle's railway vehicle products to reporters.
