Đường sắt thép Brazil 115RE là một loại đường sắt hạng nặng được sử dụng chủ yếu trong các tuyến đường sắt cho các hệ thống giao thông ở Brazil và các quốc gia khác áp dụng các thông số kỹ thuật đường sắt tương tự. This steel rail is manufactured to withstand high traffic loads and the harsh environmental conditions often found in Brazil, from the humid Amazon rainforest to the arid regions of the northeast. It is engineered for high performance and longevity, making it suitable for mainline railways, heavy-haul tracks, and other demanding applications.
Drawing of Brazil 115RE steel rail
The 115RE rail profile has a wider base and a thicker web compared to lighter rail sections. This design provides greater stability and strength, allowing it to support heavier locomotives and freight cars. The wider base also helps distribute the load over a larger area of the track bed, reducing the likelihood of track deformation and maintaining the integrity of the rail line over time.
The rail is typically made from high-quality steel with strict adherence to alloy composition and heat treatment processes to ensure the material has the necessary tensile strength, độ cứng, và khả năng chống mài mòn và mệt mỏi. The steel composition often includes carbon, mangan, silic, and other alloying elements that contribute to the rail’s robust mechanical properties.
Brazil 115RE steel rail can be found in various lengths, with longer sections used to minimize the number of joints in the track. Fewer joints translate to a smoother ride for trains and lower maintenance requirements for the rail infrastructure. The rail is also compatible with a range of fastening systems, which secure it to the sleeper and allow for adjustments in gauge and alignment as needed.
This type of rail is integral to Brazil’s freight and passenger transportation systems, playing a crucial role in the country’s economy by facilitating the efficient movement of goods and people. As Brazil continues to develop and modernize its rail infrastructure, the 115RE steel rail remains a key component in ensuring the reliability and safety of its railway network.
