GB Standard Steel Rail Railway Rail Heavy Duty Factory Price Steel Rail Strong And Durable Suitable For Construction And So On
In a sense, wholesale rail products development is also the history of railway development. Without the advancement of rail technology, heavy-duty and high-speed railway technology is difficult to develop. The quality of rails has an important impact on the safety and efficiency of railway transportation.
Before the industrial revolution in Europe, the tracks were made of long timbers with a width of several inches. Under the wooden track, a piece of wood was placed horizontally every two to three feet as sleepers. The sleepers were mainly used to fix the wooden track so that It maintains the specified width. The wheels running above it were also made of wood. At that time, steel could not be produced on a large scale, and iron was also a very expensive material. The wooden track was easy to wear and tear. Later, people pasted thin long iron sheets on its surface and fixed them with nails. On the track, this not only prolongs the service life of the track, but also reduces frictional resistance, which is the most primitive rail.
PRODUCT PRODUCTION PROCESS
Technology and Construction Process
The process of constructing Train Railroad Tracks 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 rails 10m, 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.
The type and strength of Train Rail Steel are expressed by the approximate mass (kilograms) per meter of length. For example, the current standard rail types in China are 43kg/m, 50kg/m, 60kg/m, 75kg/m, etc. The standard length of rails in China: 43kg/m is 12.5m or 25m; the length of rails above 50kg/m is 25m, 50m, and 100m. Go to the rail welding factory to weld it into a 500m long rail, and then transport it to the construction site and weld it into the required length.

APPLICATION
Railroad Track Rail head section design is also one of the ways to improve stiffness and wear resistance.
In the rail head section of the early rail, 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.
First, countries have followed such a principle in the design of the rail head tread: the arc of the rail top tread conforms to the size of the wheel tread as much as possible, that is, the size of the tread arc, such as the 59.9kg/m rail in the United States, the rail head arc is adopted R254-R31.75-R9.52; the 65kg/m rail of the former Soviet Union, the rail head arc adopts R300-R80-R15; the UIC 60kg/m rail, the rail head arc adopts R300-R80-R13. It can be seen from the above that the main feature of the section design of the modern rail head is the use of complex curves and three radii. On the side of the rail head, a straight line with a narrow top and a wide bottom is adopted, and the slope of the straight line is generally 1:20~1:40. A straight line with a large slope is often used at the lower jaw of the rail head, and the slope is generally 1:3 to 1:4.
Second, in the transition zone between the rail 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.
PACKAGING AND SHIPPING
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 transportation of high-speed rail rails requires the help of professional transportation equipment and teams. Generally speaking, high-speed rail rails are transported by rail. In the early stages of domestic high-speed railway construction, some key equipment and materials needed to be imported from abroad. At that time, air transportation was a common mode of transportation. However, high-speed rail rails that are independently developed and manufactured are generally transported by the railway itself. Each high-speed rail is about 25 meters long and weighs 30 tons. It often requires two carriages at the front and rear to complete the entire transportation process. Therefore, before transportation, it is necessary to carefully plan the route and pre-check whether the carriage meets the transportation requirements to ensure that no damage or safety accidents will occur during transportation.
