Product Introduction
GB heavy rail is a heavy rail material produced in accordance with national standards. It adopts advanced production technology and high-quality raw materials, has good comprehensive performance, and can provide solid guarantee for railway transportation. GB 50KG heavy rail is a member of the GB heavy rail system. The weight of 50 kilograms per meter makes it widely used in rail engineering, especially suitable for some railway lines with moderate requirements for rail weight.
50kg/m coal mine heavy rail is a type of rail commonly used in coal mine underground rail transportation system.
The weight of 50kg per meter makes it have high strength and rigidity, and can withstand the large load of coal mine underground transportation vehicles, including the weight of materials such as coal and gangue, as well as the impact force of vehicles during operation, to ensure transportation safety. The underground environment of coal mines is harsh, and the rail wear is relatively serious. 50kg/m heavy rails usually use wear-resistant materials such as U71Mn, which have high surface hardness and excellent wear resistance. They can effectively resist wheel wear, extend the service life of the rail, and reduce the frequency of maintenance and replacement.
