Product Introduction
GB heavy rails are manufactured according to China's national standard (GB) and are used for laying railway tracks and carrying heavy rails for train operation. In terms of conventional production technology, steelmaking, rolling, heat treatment and other processes are mainly used. In the steelmaking process, high-quality carbon structural steel is usually selected, with molten iron as the main raw material, smelted in a converter or electric furnace, and the content of carbon, manganese, silicon and other elements and the proportion of impurities in the steel are strictly controlled to ensure the strength and toughness of the steel. After the billet is formed, it is rolled through multiple rolling processes to gradually form a specific I-shaped cross-section of the steel. This shape can effectively disperse the train load and enhance the compression and bending resistance of the rail. After rolling is completed, it is also necessary to carry out processes such as cutting to length and straightening to ensure that the dimensional accuracy of the rail meets the standard requirements. With its stable performance and precise specifications, GB heavy rails are widely used in trunk railways, urban rail transit and other fields, providing solid guarantees for the safe and smooth operation of trains.
50KG national standard heavy rails refer to rails with a nominal weight of about 50 kilograms per meter. They are mainly used for laying railway tracks, especially for 20-50 ton traveling vehicles, overhead cranes, crane special rails, and coal transportation lines in power plants. They mainly include U71Mn, 50Mn, etc. U71Mn rails have higher strength and wear resistance, while 50Mn rails have better toughness and comprehensive performance.

First, use a special cleaning agent to remove impurities and oil stains on the surface of the rails to ensure the effectiveness of the anti-rust treatment. Then use manual brushing to evenly apply anti-rust oil, focusing on the rail head, rail bottom and other easily corroded parts. After the anti-rust oil is slightly dry, use anti-rust paper to wrap each rail, and then cover the outer layer with a layer of thickened anti-rust canvas.
