Heavy Industrial Rail Track Used Rail Steel Main Component of Railway Track and Track Circuit Q275 20Mnk Rail Steel

Steel rails are typically manufactured in standard lengths of 30 feet, 39 feet, or 60 feet, although longer rails can also be produced for specific projects. The most common type of steel rail used in railway tracks is known as flat-bottomed rail, which has a flat base and two angled sides. The weight of the rail, known as its "poundage," varies depending on the specific requirements of the railway line.

The production process of steel rails involves several steps, including:

1. Raw material preparation: The production of steel rails begins with the selection and preparation of raw materials, typically high-quality steel billets. These billets are made from iron ore and other additives, such as limestone and coke, which are melted in a blast furnace to produce molten iron.
2. Continuous casting: The molten iron is then transferred to a continuous casting machine, where it is poured into molds to form long continuous strands called billets. These billets are typically rectangular in shape and provide the starting material for the rail production process.
3. Heating and rolling: The billets are reheated in a furnace to a temperature that allows them to be easily shaped and rolled. They are then passed through a series of rolling mills, which exert tremendous pressure to shape the billets into the desired rail profile. The rolling process involves multiple repetitions of passing the billets through the rolling mills to gradually shape them into rails.
4. Cooling and cutting: After the rolling process, the rails are cooled and cut to the required length. They are typically cut into standard lengths of 30 feet, 39 feet, or 60 feet, although longer rails can also be produced for specific projects.
5. Inspection and treatment: The finished rails undergo rigorous inspection to ensure they meet industry standards and specifications. Various tests, such as dimensional measurements, chemical analysis, and mechanical testing, are conducted to verify the quality and integrity of the rails. Any defects or imperfections are identified and attended to.
6. Surface treatment: To enhance the durability and corrosion resistance of the rails, they may undergo surface treatment processes. This can include applying protective coatings, such as anti-corrosion paint or galvanization, to prevent rust and corrosion, thereby extending the lifespan of the rails.
7. Final inspection and packaging: Once the rails have been treated and pass the final inspection, they are carefully packaged for transportation to rail construction sites. The packaging is designed to protect the rails from any damage during transit.
