Professional Custom GB Standard Steel Rail Standard Grade Heavy Type Railway Steel Railing Rail
The strength, wear resistance and impact resistance of Railroad Track for sale depend to a large extent on the material of the rail, that is, on the chemical composition, metallographic organization, production process and heat treatment quality of the steel. The chemical composition of the rail, in addition to iron, also contains carbon, manganese, silicon, sulfur and phosphorus. High carbon content can increase the strength of the rail, but too high carbon content will reduce its plastic and impact toughness. Increasing the content of manganese and silicon can increase the strength, hardness and toughness of the rail. Sulfur and phosphorus are harmful impurities and should not be allowed to exceed the prescribed limits. In addition, adding an appropriate amount of chromium, nickel, molybdenum, vanadium, titanium or copper to the rail to make alloy rail, can improve the quality of the rail. Since the 1970s, China has produced low-alloy steel rails containing rare earth, low manganese, medium silicon, titanium and copper. In order to improve the anti-wear energy of the rail end part, prevent crushing and ensure the uniform wear of the rail, the rail surface quenching is usually carried out at both ends of the rail to improve its hardness; Full length quenching, better rail use effect.
PRODUCT PRODUCTION PROCESS
Technology and Construction Process
The process of constructing train track steel 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.

ADVANTAGE
Sort by weight. The type of rail is usually differentiated according to the weight, for example, we often say 50 rail, which refers to the weight of 50kg/m rail, and so on, there are 38 rail, 43 rail, 50 rail, 60 rail, 75 rail, etc., of course, there are 24 rail, 18 rail, but that is the old age. Rails with 43 rails and above are generally called heavy rails.
The cross-sectional shape of the rail consists of a bend-resistant I-shaped section and consists of a rail head, a rail waist and a rail bottom. In order for the rail guide to better withstand various forces and ensure the necessary strength conditions, the guide rail should have sufficient height, the head and bottom should have sufficient area and height, and the waist and bottom should not be too thin.
In order to facilitate statistical analysis and analysis of railway damage, railway damage needs to be classified. According to the damaged location of the rail track section, the occurrence of damage and the cause of the damage, it is divided into 9 types and 32 types of injuries, divided into two digits. A ten-digit number indicates the location and status of the damage, and a single number indicates the cause of the damage.
Side wear occurs on the outer links of small radius curves and is one of the main types of damage on curves. When the train runs on a curve, the friction and sliding of the rail wheel rails are the fundamental cause of side rail grinding. When a train passes through a small radius curve, there are usually two points of contact between the wheels and the track, and there is a lot of side grinding. The size of the side grind can be expressed by the product of the guiding force and the impact angle, that is, the wear coefficient. Improving the conditions for trains to pass curves, such as using worn wheel treads, using radial bogies, etc. will reduce the speed of side grinding.

APPLICATION
Classified by manufacturing process. According to the classification of manufacturing process, rail can be mainly divided into hot rolled rail and heat treatment rail. In fact, the rail is produced by the hot rolling process, the heat treatment rail is in the hot rolling molding of the rail for heat treatment again, divided into online heat treatment and offline heat treatment of two kinds, online heat treatment is already the mainstream, more energy saving and more efficient.Railroad Track for sale

3, Characteristics and Improvement Trends of Rail Sections:
Characteristics and Improvement Trends of Rail Sections
The continuous increase of railway speed and axle load requires rails to have greater rigidity and better wear resistance.
In order to make the rails have sufficient thickness, the height of the rails can be increased appropriately to ensure that the rails have a large horizontal moment of inertia. At the same time, in order to make the rail have sufficient stability, the width of the rail should be selected as wide as possible when designing the width of the rail. In order to best match the stiffness and stability, countries usually control the ratio of the rail height to the bottom width, is H/B, when designing the rail section. Generally, H/B is controlled between 1.15 and 1.248. The H/B values of rails in some countries are shown in the table.
