product information
Rails are the main components of railway tracks. which function is to guide the wheels of locomotives and vehicles, to withstand the enormous pressure of the wheels, and pass them on to the sleepers. The rails must provide the wheels with a continuous, smooth and minimal rolling surface.In electrified railways or automatic block sections, rails can also serve as rail circuits.
The type of rail is expressed in kilograms per meter of rail length and can be divided into crane rails (crane rails), heavy rails and light rails. The rails are rolled with carbon-killed steel smelted by open hearth furnaces and oxygen converters. Its purpose is to withstand the operating pressure and impact load of locomotives and vehicles.
Rails are widely used and durable
Different types of steel rails have different functions. Rails are mainly used in railways, cranes and underground mines, and temporary transportation routes and light-duty locomotive use routes are laid in forest areas, factories, and construction sites.

product advantages
The cross-sectional shape of the Railway Track Steel Rail Train Rail is an I-shaped section with the best bending performance,including rail heads, rail lugs, and rail bottoms.
The bending performance is related to the cross-sectional shape. The higher the cross section, the closer the area distribution is to the upper and lower ends, and the better the bending resistance.
Heavy Railway Track Steel Rail Train Rail:38KG, 43KG, 50KG
Crane rail:QU70,QU80,QU100,QU120
The rails should be of sufficient height and their heads and bottoms should have sufficient area and height, and the waist and bottom should not be too thin.

product considerations
Rail damage refers to the occurrence of breaks, cracks, and other damages that affect the performance of rails during use of the rails. There are many kinds of rail damage, common wear, peeling and nuclear damage to the rail head, lumbar bolt hole cracks.

Rail damage
The rail wear mainly refers to the side wear and wave wear of the rail on the small radius curve. As far as vertical wear is normally normal, it increases with axial weight and total weight. The improper setting of the geometry of the track will accelerate the vertical wear rate. This is to be prevented and can be solved by adjusting the track geometry.
From the perspective of public works, the material of the rails should be improved, wear-resistant rails should be used, maintenance and repairs should be strengthened, appropriate gauges, super rails, rails, and slopes should be set to increase the flexibility of the lines. Small side wear effect.

Rail contact fatigue damage
The formation of the contact fatigue of the railhead, due to insufficient metal contact fatigue strength and multiple actions of heavy-duty wheels, will cause the point to become a plastic zone when the maximum shear stress point exceeds the shear yield limit. The sliding of metal microstructures, through the operation of a period of time, causes the accumulation and accumulation of such slips, which eventually leads to the formation of fatigue cracks.
With the improvement of the axle load, the transportation conditions of the large transport volume, the non-adaptability of rail materials and rail types, the initiation and development of contact fatigue cracks will be accelerated.
