Use industry strength and quality to create industry leadership
The deep processing of steel rolling and steel is mainly based on rolling and deep processing of steel rails, steel sheet piles and various special-shaped steels, with an annual production capacity of about 2 million tons. In the production process, the products with high technology content and difficult rolling are marching forward. For example, the grooved steel rails, which are known as the “king of the rails”, have won the bids for Beijing, Shanghai, Yunnan, Nanjing and Zhuhai. Modern urban tramcar projects in more than ten cities including Changchun and Shenyang. In addition, last year's first Changsha medium and low speed magnetic levitation line rail (F rail) was also designed, developed, produced and supplied by our company. At the same time, other specifications of the rails are also exported to more than 60 countries and regions around the world, and rail accessories have been exported to dozens of high-end markets in Australia, the United States, Germany and other countries.
The grooved track is known as the "king of the rail". The rail has an asymmetrical groove on the rail head and is complex in shape, making it the most difficult to roll in the rail. At present, only a few countries such as Germany have mastered the production technology of such rails. The new trough-type rails have extremely high requirements on the section accuracy, so higher requirements are also placed on the hole design and process control of the universal mill.
Medium and low speed magnetic levitation is a new technology with independent intellectual property rights in China, and it is also the most advanced technology in urban rail transit. It has the advantages of environmental protection, high safety, strong climbing ability, small turning radius and low construction cost. It is suitable for traffic connections between urban areas, close-range cities and tourist attractions, and can replace light rail and subway. Changsha magnetic levitation is the first independent design, self-manufacturing and independent application in China...
Heavy rail is applied to passenger transport railways in various countries.
