Products Description
22kg mining rails are rails specially used for railway transportation in underground mines or open-pit mines, with a theoretical weight of 22 kg per meter.
Compared with some standard railway rails, 22kg mining rails are relatively light, which is convenient for laying, handling and installation in specific environments such as mines, reducing construction difficulty and labor intensity.
Although it is light in weight, it still has sufficient strength and toughness to withstand the load of mining transportation vehicles and the impact force during operation, meeting the use requirements of mining transportation.
The mining environment is usually harsh, with high humidity and corrosive gases. 22kg mining rails are generally made of special materials or anti-corrosion treatment to improve their corrosion resistance and extend their service life.

Other Features
National standard steel rails have the following characteristics:
High dimensional accuracy:
Produced strictly in accordance with national standards, the error of dimensional parameters such as length, width, height, and thickness is controlled within a very small range. For example, the length of steel rails usually has standard specifications such as 12.5 meters and 25 meters, and the length error generally does not exceed ± 6 millimeters; The tolerance of cross-sectional dimensions is also strictly regulated, which ensures the tightness of the connection between rails and the flatness of the track, providing a guarantee for the smooth operation of trains.
Excellent material performance:
Made of specific alloy steel material, it has high strength, high toughness, high wear resistance, and good fatigue resistance. Taking the common U71Mn steel rail as an example, its tensile strength can reach over 880MPa, and its elongation at break is not less than 9%. It can withstand the huge load and frequent impact vibration of trains, and is not prone to wear, cracks and other defects during long-term use, which extends the service life of the rail.

FAQ
What is the main purpose of steel rails?
Answer: Steel rails are mainly used in railway and rail transit systems, and are the foundation of train operation. They support the operation of the train, bearing the weight, dynamic load, and friction of the train.
What are the types of steel rails?
Answer: Steel rails are mainly divided into heavy rail, light rail, mining rail, etc. according to their different uses and specifications. Heavy rail is usually used for high-speed and heavy-duty railways, light rail is used for urban rail transit, and mining tracks are suitable for mining areas or industrial railways.
How is the weight of steel rails defined?
Answer: The weight of steel rails refers to the weight per meter of track. For example, a 22kg steel rail represents a weight of 22 kilograms per meter of track. Different railway systems select rails of different weights according to load requirements.
