75kg/m GB heavy rail is an important type of rail used in railway tracks. It adopts advanced processes such as converter steelmaking and universal rolling. Converter steelmaking can effectively control the composition and temperature of molten steel and ensure the quality of molten steel. Universal rolling can accurately control the geometric size and straightness of the rail and improve the accuracy and surface quality of the rail.
Mainly used in heavy-duty railways, such as Daqin Railway. Daqin Railway is the first heavy-duty railway in China. It has a huge transportation volume and extremely high requirements for the bearing capacity and wear resistance of the rail. 75kg/m rail can well meet its use requirements and ensure the safe and efficient operation of the railway.
Steel strapping has the advantages of high strength, corrosion resistance and low cost. Galvanized steel strapping is usually used for bundling, and each bundle of heavy rails is tied at least 3-4 times to ensure that they will not loosen during long-distance sea transportation. Before bundling, the surface of the heavy rails needs to be coated with anti-rust oil and covered with a layer of anti-rust cloth to prevent the steel straps from directly contacting the rail surface and causing indentations.
