The rail is made of carbon killed steel smelted by open hearth and oxygen converter. Its purpose is to withstand the operating pressure and impact load of rolling stock.
PRODUCT PRODUCTION PROCESS
Technology and Construction Process
The process of constructing china steel rail tracks involves precision engineering and careful consideration of various factors. It begins with designing the track layout, taking into account the intended usage, train speeds, and terrain. Once the design is finalized, the construction process commences with the following key steps:
1. Excavation and Foundation: The construction crew prepares the ground by excavating the area and creating a sturdy foundation to support the weight and stress imposed by trains.
2. Ballast Installation: A layer of crushed stone, known as ballast, is laid on the prepared surface. This serves as a shock-absorbing layer, providing stability, and helping to distribute the load evenly.
3. Ties and Fastening: Wooden or concrete ties are then installed on top of the ballast, imitating a frame-like structure. These ties offer a secure base for the steel railroad tracks. They are fastened using specific spikes or clips, ensuring they remain firmly in place.
4. Rail Installation: The steel railroad tracks, often referred to as standard rails, are meticulously laid on top of the ties. Being made of high-quality steel, these tracks possess remarkable strength and durability.

ADVANTAGE
In the rail head section of the early Galvanised Rails, the tread surface is relatively gentle, and the arcs with smaller radius are used on both sides. Until the 1950s and 1960s, it was found that regardless of the shape of the originally designed rail head, after the wear of the train wheels, the shape of the tread on the top of the rail was almost all circular, and the radius of the arc on both sides was relatively large. The experimental simulation found that the peeling of the rail head is related to the excessive wheel-rail contact stress at the inner fillet of the rail head. In order to reduce the damage of rail stripping, all countries have modified the arc design of the rail head to minimize the plastic deformation.
PROJECT
Our company’s Railroad Track for sale 13,800 tons of steel rails exported to the United States were shipped at Tianjin Port at one time. The construction project was completed with the last rail being steadily laid on the railway line. These rails are all from the universal production line of our rail and steel beam factory, using global Produced to the highest and most rigorous technical standards.

APPLICATION
Ordinary rail is the most widely used type of rail in domestic railways. Its cross-section is "mouth" shaped, with a height of 136mm, a waist width of 114mm, and a base width of 76mm. The weight of ordinary rails is divided into various specifications such as 50kg, 60kg, and 75kg. It is characterized by a relatively low price and is suitable for areas where the transportation weight is not too heavy and the speed is not too fast.
There are various types of rails. According to different usage scenarios and requirements, choosing the right rail can improve the operating efficiency and safety of the railway. In railway construction, it is recommended to choose the appropriate type of rail to give full play to its advantages.
PACKAGING AND SHIPPING
in the transition zone between the railway steel head and the rail waist, in order to reduce the cracks caused by stress concentration and increase the frictional resistance between the fishplate and the rail, a complex curve is also used in the transition area between the rail head and the rail waist, and a large radius design is adopted in the waist. For example, UIC's 60kg/m rail uses R7-R35-R120 in the transition zone between the rail head and the waist. Japan's 60kg/m rail uses R19-R19-R500 in the transition zone between the rail head and the waist.
in the transition zone between the rail waist and the rail bottom, in order to achieve a smooth transition of the section, a complex curve design is also adopted, and the gradual transition is smoothly connected with the slope of the rail bottom. Such as UIC60kg/m rail, is to use R120-R35-R7. Japan's 60kg/m rail uses R500-R19. China's 60kg/m rail uses R400-R20.
the bottom of the rail bottom is all flat, so that the section has good stability. The end faces of the rail bottom are all at right angles, and then rounded with a small radius, usually R4~R2. The inner side of the rail bottom is usually designed with two sets of oblique lines, some of which adopt double slope, and some adopt single slope. For example, UIC60kg/m rail adopts 1:275+1:14 double slope. Japan's 60kg/m rail adopts 1:4 single slope. China's 60kg/m rail adopts 1:3+1:9 double slope.
