GB heavy rail, that is, heavy rail that meets national standards, plays a key role in many fields. Because it needs to carry heavy vehicles, the rails are thick and heavy, and the specifications are high.
Railway trunk lines are an important application scenario for GB heavy rails. In national railway trunk lines, high-speed railways and heavy-load railways, trains run at high speeds and carry heavy loads. Heavy rails have to withstand huge pressure, impact loads and long-term friction from locomotives and vehicles. For example, in China's high-speed rail network, a large number of heavy rails of 60kg/m and above are used, such as the Beijing-Shanghai high-speed railway, which ensures the safety and stability of high-speed trains. Heavy rails are required to have high strength, high toughness and good wear resistance to ensure long-term stable operation of railways.
The subway system in urban rail transit is also inseparable from GB heavy rails. Subway trains frequently start and stop, and the passenger flow is large, which places strict requirements on the rail system. Heavy rails can provide reliable support for subway trains and ensure safe and comfortable operation. For example, the subway networks in large cities such as Beijing and Shanghai are equipped with a large number of standard heavy rails to meet the needs of high-density operations, and can withstand frequent heavy load impacts and reduce maintenance costs.
In the industrial field, GB heavy rails are often used for large crane tracks. In places such as steel mills and ports, cranes lift heavy objects, and heavy rails need to withstand huge vertical pressure and horizontal tension. Crane rails such as QU100 and QU120 belong to the category of heavy rails, which can ensure the smooth operation and accurate positioning of cranes, prevent accidents such as derailment, and ensure safe and efficient industrial production.
In addition, some special railway lines, such as mining railways and forest railways, will also use GB heavy rails due to complex transportation environments and variable loads. The high strength and stability of heavy rails can adapt to harsh conditions and ensure smooth material transportation.
