Product Introduction
GB heavy rails are standardized railway components made of U71Mn and U75V low alloy steels. Their production process integrates microalloying and online heat treatment technology. During steelmaking, the manganese and vanadium content is precisely controlled by the LF furnace; during rolling, a low-temperature rolling process is used to promote the precipitation and strengthening of vanadium elements; the rail head adopts dual-frequency induction quenching technology, first heated to 900℃ for austenitization with medium frequency (2-10kHz), and then rapidly cooled with high frequency (80-100kHz) to form a "fine martensite + residual austenite" hardened layer with a depth of 10mm and a uniform hardness gradient, which improves the rail's anti-peeling performance by 40%.
50kg GB heavy rail is a kind of rail widely used in railway construction and other fields. The standard length is usually 12.5m and 25m. This length design is convenient for transportation and laying, and can meet the construction needs of different lines.
Material characteristics: Commonly used materials are U71Mn, etc. This steel has high strength and good toughness, and can withstand the pressure, impact load and friction during train operation. At the same time, U71Mn material also has certain wear resistance and corrosion resistance, which can extend the service life of the rail and reduce maintenance costs.
