The manufacture process of cold drawn seamless steel tubes involves several steps to achieve the desired dimensions, surface finish, and mechanical properties. Here is a general overview of the process:
Raw Material Selection: The process begins with the selection of high-quality steel billets or solid bars. The choice of steel grade depends on the specific application and requirements of the seamless steel tube.
Heating: The selected steel billets are heated in a furnace to a temperature suitable for the subsequent forming process. This heating process helps to improve the malleability and ductility of the steel.
Piercing: The heated steel billet is then pierced by a piercing mill or a rotary piercing machine. This process involves forcing a pointed mandrel through the center of the billet to create a hollow tube.
Extrusion: The pierced billet is then passed through an extrusion mill, where it is elongated and reduced in diameter to achieve the desired dimensions. This process is performed at elevated temperatures to ensure proper plastic deformation of the steel.
Cold Drawing: After extrusion, the tube is cooled and then subjected to a cold drawing process. In this step, the tube is pulled through a series of dies with progressively smaller diameters. This cold drawing process helps to refine the dimensions, improve the surface finish, and enhance the mechanical properties of the steel tube.
Annealing: To relieve internal stresses and improve the ductility of the steel, the cold-drawn tube is typically subjected to an annealing process. The tube is heated to a specific temperature and held for a certain period of time, followed by controlled cooling. This annealing process also helps to improve the machinability and formability of the steel tube.
Surface Treatment: Depending on the application and customer requirements, the cold drawn seamless steel tube may undergo additional surface treatments such as pickling, passivation, or polishing to achieve the desired surface finish and remove any impurities or scale.
Final Inspection and Testing: The manufactured cold drawn seamless steel tubes undergo rigorous inspection and testing to ensure they meet the required specifications and quality standards. This includes dimensional checks, visual inspection, non-destructive testing, and mechanical property testing.
Packaging and Delivery: Once the tubes pass the final inspection, they are properly packaged to protect them during transportation and storage. The tubes are then delivered to the customers or stored for future use.
It's important to note that the specific manufacturing process may vary depending on the equipment and techniques used by different manufacturers. Additionally, certain variations and additional steps may be incorporated to meet specific customer requirements or industry standards.
