Product Introduction
As a standardized railway construction material, GB heavy rail plays a key role in important lines such as railway trunk lines with its scientific design and manufacturing process; GB 75KG heavy rail, with its specific weight specifications, further improves the stability and reliability of the track system, providing a solid guarantee for the smooth and safe operation of trains.
75KG heavy rails can withstand the heavy axle weight and frequent loads of mine cars in underground mining, adapt to long-term, high-intensity transportation operations, reduce track deformation and damage, and ensure transportation safety. The 75KG heavy rails are large in size and have a large contact surface with the sleepers, which can well disperse the train load, improve the stability and smoothness of the track, effectively improve the operation efficiency, reduce equipment wear, extend the service life of the rails, and reduce the cost of later maintenance.
Using U75V material, through online heat treatment process, the hardness of the rails is greatly improved, and the toughness is also enhanced, which can well cope with the impact force generated by the train during braking and braking.

Maintenance points
Regular inspection: Due to the harsh underground mining environment, the rails are susceptible to impact and wear, and it is necessary to regularly check the wear, deformation, cracks, etc. of the rails.
Cleaning and lubrication: Remove slag, dust and other debris on the track in time to prevent them from entering between the track components and aggravating wear.
Ballast bed maintenance: Maintain the density and flatness of the ballast bed, add ballast in time, and tamp the ballast bed to provide good elasticity and support, and reduce the vibration and fatigue of the track. Effectively resist the wear of the mine car wheels, extend the service life of the track, and reduce the cost of mining and transportation.
