Product Introduction

GB heavy rails are the core bearing components of railway tracks, and their performance indicators and technical parameters are strictly and clearly specified. In terms of materials, they mainly use high-carbon manganese steel U71Mn, vanadium-containing high-carbon steel U75V and other materials. Through scientific and reasonable alloy composition design and precise smelting control, the heavy rails are given excellent comprehensive performance. ​

In terms of mechanical properties, the tensile strength of GB heavy rails usually needs to reach more than 900MPa, the yield strength is not less than 600MPa, and the elongation is ≥10%. It has high strength and good toughness, and can withstand the huge dynamic load of train wheels and frequent alternating stress. The rail head part is treated by quenching-tempering process to make its surface hardness reach 330-380HBW, forming a high-strength wear-resistant layer, which effectively resists wheel wear and plastic deformation; the rail waist and rail bottom are treated by reasonable structural design and size optimization to ensure sufficient support strength and stability, which can effectively disperse stress and reduce rail deformation when the train is running.

60KG means that the weight of each meter of track is 60 kilograms. This specification belongs to the category of heavy-duty track in railway construction. It can withstand greater loads and higher operating speeds. It is suitable for lines such as trunk railways and high-speed railways that have strict requirements on track performance. Compared with lighter specifications such as 50KG, 60KG track has significant advantages in stability and carrying capacity, which can ensure the safe, smooth and efficient operation of trains.

U71Mn is a common manganese-containing rail, in which manganese (Mn) plays an important role. Manganese can increase the strength and hardness of steel, while improving the toughness of steel. U71Mn 60KG heavy rail has good comprehensive performance, achieving a good balance between strength, hardness and toughness, and can meet the use requirements of general railway trunk lines.

In terms of strength and wear resistance, U75V track is superior to U71Mn track due to its special alloy composition and optimized microstructure. The higher tensile strength and hardness of U75V 60KG heavy rails make them more suitable for high-speed and heavy-load railways. The toughness of U71Mn rails is also good, and the cost advantage is obvious.

Product Application

Product Packaging & Delivery

To ensure the integrity of GB heavy rails during transportation, the packaging adopts a double fixation and double protection strategy. The rails are first stacked into a rectangle according to the standard number, and high-strength steel wires are used to cross-bundle the four corners to form a stable frame. Then, thickened steel belts are used for surrounding reinforcement, and the joints of the steel belts are double-treated with locks and welding. In the anti-rust process, the surface of the rails is first degreased and cleaned, then sprayed with anti-rust oil, and then covered with a layer of anti-rust paper. The corrosion-inhibiting gas released by the paper inhibits the formation of rust. The outermost layer is wrapped with tear-resistant plastic film to provide all-round protection for the rails.
