Hot rolled steel plate is a kind of hot working steel, widely used in shipbuilding, construction, machinery, automobile and other industries. Compared with cold rolled steel plate, hot rolled steel plate processing temperature is higher, can make the steel in the process of plastic deformation more easily, but also can greatly improve the mechanical properties of steel plate.

The production process of hot rolled steel plate is generally divided into raw material treatment, hot rolling, surface treatment and cooling. First, the raw material is pickled, cut and straightened to remove surface oxides and impurities, making it suitable for hot rolling. Then, under high temperature conditions, the steel plate is sent to a hot mill for processing, where it undergoes a large plastic deformation under high temperature conditions to form the desired shape and thickness. Then, after pickling, acid phosphating and other surface treatment process, can improve the corrosion resistance of the steel plate, avoid rust and other problems in the process of use. Finally, the steel plate is cooled so that its temperature is gradually reduced, thus improving the mechanical properties of the steel plate and the quality of the finished product.

Hot rolled steel plate is widely used in construction, machinery, ships and other fields because of its excellent properties. In construction, hot-rolled steel plates can be used to make Bridges, high-rise buildings, pipes and structural parts, which can improve the stability and safety of buildings. In the field of machinery, hot rolled steel plates can be used to manufacture various machinery equipment and parts, which can improve the quality and durability of machinery. In the field of ships, hot rolled steel plates can be used in the manufacture of various ship structural parts, which can improve the strength and safety of ships.

In short, hot rolled steel plate is an important building and manufacturing material, and its processing technology and excellent properties make it widely used.
