The production process of AREMA standard steel rail usually includes the following steps:
Raw material preparation: Prepare raw materials for steel, usually high-quality carbon structural steel or low alloy steel.
Smelting and casting: The raw materials are smelted, and then the molten steel is cast into preliminary steel billets through continuous casting or pouring.
Refining and rolling: Refining the preliminary steel billet, including removing impurities and adjusting the composition, and then rolling the steel billet through rolling equipment into track billets that meet national standards.
Pretreatment: Pretreatment of track billets, including forging, heat treatment and surface treatment, etc., to improve the strength and durability of the rails.
Rolling and forming: The pre-treated track billet is rolled and formed through a rolling machine to make it into a rail profile that meets the national standard requirements.
Inspection and quality control: Strict inspection and quality control are carried out on the produced rails to ensure that they meet national standards and customer requirements.
Packaging and leaving the factory: Qualified rails are packaged and marked, and then delivered to the customer or stored in the warehouse waiting for shipment.
ASTM standard steel rail have the following characteristics:
High strength: American standard rails are made of high-quality steel, which has high strength and durability and can withstand the heavy pressure and operating impact of trains.
Standardization of specifications: The specifications and dimensions of American standard rails are strictly formulated in accordance with the standards, ensuring the uniformity and interchangeability of the railway system.
Strong wear resistance: The surface of American standard rails has been specially treated and has strong wear resistance, which can reduce track wear and extend service life.
Good corrosion resistance: The surface of American standard rails has undergone anti-corrosion treatment, which can resist oxidation and corrosion and maintain good use condition.
Wide scope of application: American standard rails are suitable for various railway lines, including high-speed railways, ordinary railways and freight railways, etc., and have strong versatility and applicability.
