Product Description
Production Process
Hot-rolled plate is produced by heating steel billets to a high temperature, usually above 1000°C, and then rolling them through a series of rolling mills. The high temperature makes the steel more malleable, allowing it to be easily shaped into the desired thickness and width. After rolling, the plate is cooled down rapidly to room temperature, either by natural air cooling or by using water cooling systems.
Properties
Good Mechanical Properties: Hot-rolled plates have excellent strength, toughness, and ductility. These properties make them suitable for applications that require high load - bearing capacity and resistance to deformation.
Uniform Structure: The hot - rolling process helps to refine the grain structure of the steel, resulting in a more uniform and dense material. This uniformity contributes to consistent mechanical properties throughout the plate.
Good Surface Quality: Although the surface of hot - rolled plates may not be as smooth as that of cold - rolled plates, modern production techniques have significantly improved the surface finish. They can have a relatively clean and smooth surface, suitable for many applications without the need for additional surface treatment.
Q355B Manganese Hot Rolled Carbon Steel Coil (ASTM A572 Grade 50)
Manganese is the key alloying element, usually present in a certain proportion. The addition of manganese can significantly improve the strength and toughness of the steel plate. It enhances the ability of the plate to withstand large loads and impacts, making it suitable for applications in harsh working conditions. Manganese plates often exhibit good wear - resistance properties. This is because manganese can refine the grain structure of the steel, making the surface more resistant to abrasion and prolonging the service life of the plate in applications involving friction and wear.
Applications
Construction Industry: It is widely used in the construction of buildings, bridges, and other infrastructure projects. Hot - rolled plates are used for structural components such as beams, columns, and floor decks, providing the necessary strength and stability.
Mechanical Engineering: In the manufacturing of machinery and equipment, hot - rolled plates are used for parts such as machine beds, frames, and gears. Their high strength and good machinability make them ideal for these applications.
Automotive Industry: Hot - rolled plates are used in the production of automobile bodies, chassis, and various automotive components. They offer a good balance of strength and formability, allowing for the production of complex - shaped parts.
Pipeline Industry: Hot - rolled plates are often used to manufacture pipes for transporting oil, gas, and water. The plates are rolled and welded to form pipes with different diameters and wall thicknesses, meeting the requirements of different pipeline applications.

Flame Cutting
Utilizes the high - temperature flame generated by the combustion of a combustible gas (such as acetylene, propane, etc.) mixed with oxygen to heat the metal material above its ignition point or melting point. Then, high - pressure oxygen flow is used to blow away the molten slag, thereby achieving the cutting of the metal. During the cutting process, the metal is oxidized and melted to form a cut.
