The 75kg steel rail according to Chinese standards is a high-strength and high wear-resistant heat-treated rail, mainly used to withstand enormous pressure and wear, suitable for railway lines that require high strength and high wear resistance.
This type of steel rail is also commonly used on high-capacity and high-speed railway lines to meet the needs of high-speed and heavy-duty railways.
Heavy Steel Rail
Heavy Steel Rail | Size | Rail Height | Bottom Width | Head Width | Web Thickness | Weightkg/m |
38kg | 134 | 114 | 68 | 13 | 38.733 | |
43kg | 140 | 114 | 70 | 14.5 | 44.653 | |
50kg | 152 | 132 | 70 | 15.5 | 51.514 | |
60kg | 176 | 150 | 73 | 16.5 | 60.8 | |
75kg | 192 | 150 | 75 | 20 | 74.64 |
The production process of 75 kg heavy-duty steel rails requires strict control over the quality of raw materials, smelting processes, rolling processes, and other aspects to ensure the performance and quality of the products.
In addition to the requirements for chemical composition and mechanical properties, 75 kg heavy-duty steel rails also need to undergo drop hammer tests, acid corrosion low magnification microstructure inspections, etc. to evaluate the fatigue resistance, compressive fracture resistance, and brittle fracture resistance of this type of rail.
Q:Can the length and specifications of the rails be customized?
A:Yes, according to customer needs, we can provide rails of different lengths and specifications, and customize them according to railway design requirements.
Q:What is the manufacturing process of the rails?
A:We use advanced arc furnace steelmaking, continuous casting, rolling and other processes to ensure the high strength and wear resistance of the rails.
Q:What is the weight of the rails?
A:The weight of the rails depends on their specifications, generally ranging from 30 kg to 70 kg per meter, and special specifications can be customized according to needs.
Q:How durable are the rails?
A:Our rails have extremely high wear resistance and compression resistance, can adapt to high loads and harsh environments, and have a service life of more than 20 years.
