EN13674-4 45E1 steel rail can be used in areas with harsh weather conditions, such as extreme cold or heat, and in areas with high levels of corrosion and wear.
The production process of EN13674-4 45E1 steel rail typically includes the following steps:
1. Raw materials: Start with high-quality steel billets that meet the requirements of EN13674-4 standard.
2. Heating: Heat the steel billets in a reheat furnace to a temperature suitable for rolling and shaping.
3. Rolling: Hot-roll the billets into the desired shape, using a rolling mill. This process involves passing the heated billets through a series of rollers to form the rail shape.
4. Cooling: Allow the rail to cool slowly to room temperature in a cooling bed so that it can develop its strength and hardness.
5. Memotong: Cut the rail to the required length using a saw or guillotine.
6. End finishing: Finish the ends of the rail by cutting them at a specific angle to allow them to fit together seamlessly with other rails.
7. Kawalan kualiti: Inspect the rails to ensure compliance with EN13674-4 standards, termasuk ketepatan dimensi, Lurus, kualiti permukaan, dan sifat mekanikal.
8. Packaging and shipping: Package the rails according to customer requirements and ship them to the customer.
The production process may vary slightly depending on the specific manufacturing process and the requirements of the customer.
The 45E1 rail is a type of steel rail commonly used for heavy-duty industrial applications, such as railway tracks, trem, and subway lines. It is used in many countries around the world, including but not limited to China, Amerika Syarikat, Eropah, and South America. The use of this type of rail is dependent on the specific needs and requirements of the railway system or project where it will be applied.
