The track of a railway is not merely a linear structure but a complex system consisting of various components that ensure smooth and safe train operations. One of the most critical parts is the train rail steel. These rails serve as the foundation on which the train wheels travel, maintaining stability and minimizing the risk of derailment. Rail products, commonly made from high-quality steel, are carefully designed and manufactured to meet the dynamic demands of today's railway systems. Strength and Durability: The Backbone of Railway Steel Railway steel is produced from high-strength steel alloys, making it sturdy and exceptionally durable. It is subjected to rigorous quality control tests to ensure its ability to withstand the weight of the trains and the constant friction generated by them. The strength of rail steel is crucial as it needs to endure not only the heavy loads but also the constantly changing weather conditions. Whether it's extreme temperatures, heavy rains, or snow, the rail tracks must remain intact and operational at all times. Resistance to Wear and Tear Train rail steel also demonstrates remarkable resistance to wear and tear resulting from the immense pressure exerted by the trains' wheels. Over time, the repetitive movement of trains can cause considerable damage to the tracks. However, the surface of railway steel is designed in a way that reduces wear, minimizing the need for frequent maintenance and ensuring a longer service life. The general composition and optimized geometry of the rails enable them to withstand the daily onslaught of heavy loads, ultimately reducing operational costs for railway maintenance. Enhanced Safety Standards The trustworthy nature of rail steel plays a vital role in maintaining safety standards within the railway system. The durability and resistance of the rail tracks minimize the occurrence of accidents caused by track failures, such as cracks, fractures, or improper alignment. Additionally, the consistent surface provided by high-quality train rail steel significantly reduces the occurrence of wheel slip, preventing potential derailments and ensuring passenger safety. The reliability of railway steel makes it an essential component, especially in high-speed railway systems where the stakes are particularly high.National standard rail: Specifications: GB6kg, 8kg, GB9kg, GB12, GB15kg, 18kg, GB22kg, 24kg, GB30, P38kg, P43kg, P50kg, P60kg, QU70, QU80, QU100, QU120 Standard: GB11264-89 GB2585-2007 YB/T5055-93 Material: U71Mn/50Mn Length: 6m-12m 12.5m-25m American standard rail: Specifications: ASCE25, ASCE30, ASCE40, ASCE60,ASCE75,ASCE85,90RA,115RE,136RE,175LBs Standard: ASTM A1,AREMA Material: 700/900A/1100 Length: 6-12m, 12-25m UIC rail: Specifications: UIC50/UIC54/UIC60 Standard: UIC860 Material: 900A/1100 Length: 12-25m German standard rail: Specifications: A55, A65, A75, A100, A120, S10, S14, S18, S20, S30, S33, S41R10, S41R14, S49 Standard: DIN536 DIN5901-1955 Material: ASSZ-1/U75V/U71Mn/1100/900A/700 Length: 8-25m British standard rail: Specifications: BS50O, BS60A, BS60R, BS70A, BS75A, BS75R, BS80A, BS80R, BS90A, BS100A, BS113A Standard: BS11-1985 Material: 700/900A Length: 6-18m 8-25m Channel rail: Specifications: 59R1, 59R2, 60R1, 60R2 Standard: BS EN14811:2006 Material: ASSZ-1/U75V/U71Mn/1100/900A/700/R200/R220/R260/320Cr/R350HT Length: 8-25m Australian Rail: Specifications: 31kg, 47kg, 50kg, 60kg, 68kg, 73kg, 86kg, 89kg Standard: AS1085 Length: 8-25m European standard rail: Specifications: 49E1, 49E2, 50E1, 50E2, 50E4, 50E5, 50E6, 54E1, 54E2, 54E3, 55E1, 60E1 Specification: EN13674-1-2003 Length: 12-25m South African rails: Specifications: 15kg, 22kg, 30kg, 40kg, 48kg, 57kg Standard: ISCOR Length: 9-25mThe type and strength of rails 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.

The difference between heavy rail and light rail is that the weight per unit length of the rail is different. Rails weighing more than 30kg per meter are called heavy rails; rails weighing less than 30kg per meter are called light rails. Generally, heavy rails are mainly used on railway tracks, and hoisting rails are mainly used in lifting cuttings. The light rail is mainly used for laying temporary transportation lines and light locomotive lines in forest areas, mining areas, factories and construction sites.

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.
Methods to improve rail stiffness and wear resistance include: Choose high-strength materials: Choosing suitable rail materials, such as alloy steel or high-strength steel with good wear resistance, can improve the rigidity and wear resistance of the rails. Optimize the geometry of the rail: By changing the rail's cross-sectional shape, rail waist width, rail squat height and other parameters, the stiffness and wear resistance of the rail can be improved. Strengthen the heat treatment of rails: Through appropriate heat treatment processes, such as normalizing, quenching, etc., the strength and hardness of rails can be improved, thereby improving stiffness and wear resistance. Improve the surface hardness of the rail: Surface quenching, surface spraying of ceramic coatings and other methods can be used to increase the hardness of the rail surface and improve wear resistance. Adding appropriate alloying elements: Adding appropriate alloying elements, such as chromium, titanium, etc., to the material can increase the hardness and wear resistance of the rail. Strengthen the maintenance of rails: conduct regular inspection, repair and lubrication to keep the rails in good condition and extend their service life. It should be noted that the above methods should be selected and applied according to specific conditions and needs to achieve the purpose of improving rail stiffness and wear resistance.1.How can I get a quotation from you ?
