The uses and characteristics of GB standard rails

The production process of GB 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.
