Hot Rolled L-shaped Steel
Hot rolled L-shaped steel belongs to the category of rolled steel shaped sections, which are products shaped by pressing metal billets into desired shapes. L-shaped steel cross section has been widely used in steel structures, bridges, ships, boilers, pressure vessels and other manufacturing fields. Hot rolled L-shaped steel is one of the most popular L-shaped metal products in the market.
The purpose of hot rolling steel is to shape the metal according to the desired geometry and increase the mechanical property of the metal. Hot rolled L-shaped steel is produced by hot rolling and is usually sold in hot-rolled form. Heating usually takes place during the hot rolling process. Hot rolled L-shaped steel is thus typically chosen for engineering applications that involve high strength, ductility and toughness.
GB 9946-1988 is the national standard for hot rolled L-shaped steel. This standard was promulgated in 1988 by the Central Peoples Government of the Peoples Republic of China, and it has been revised several times since then. It sets the requirements for the size, shape, weight, etc. of hot rolled L-shaped steel products. This standard constitutes a legal basis for the quality and design of hot rolled L-shaped steel products.
The production process of hot rolled L-shaped steel is as follows: firstly, the steel billet is heated to a given temperature, and then passed through a vertical rolling mill or universal rolling mill. The heated steel billet is pressed into the desired L-shaped profile and cooled. After rolling, the product undergoes further surface treatment or finishing to improve its qualities, such as corrosion resistance.
Hot rolled L-shaped steel is available in a wide range of profiles, such as angles, tees, flats, channels, and custom-designed shapes. The advantages of hot rolled L-shaped steel include good dimensional accuracy, high strength, good weldability and corrosion resistance, as well as ease of installation. Furthermore, hot rolled L-shaped steel is cost-effective and has a wide range of applications, from manufacturing and construction to furniture and art pieces.
In summary, hot rolled L-shaped steel is a popular steel product in the market that offers many benefits, such as excellent mechanical properties, good dimensional accuracy, excellent weldability and corrosion resistance, ease of installation, and cost-effectiveness. Its use is regulated by the National Standard of the Peoples Republic of China, GB 9946-1988, which sets requirements for the size, shape, weight, etc. of hot rolled L-shaped steel products. Hot rolled L-shaped steel is thus a cost-effective and high-quality choice for many engineering projects.
