What is Angle steel?
Angle steel is a long steel bar with a right-angled cross-section. Due to its cross-sectional shape resembling an “L”, it is also called Angle iron. It is a type of steel section that is widely used in industry. Depending on different specifications, materials and applications, it can play an important role in multiple fields.
Manufacturing Process of Angle steel
- Raw material preparationCarbon structural steel, low alloy high strength structural steel and other materials are usually used as raw materials. These steels need to have good mechanical properties and processing performance. Raw materials are generally in the form of steel billets, and the size and quality of the steel billets need to meet the production requirements.
- Heating treatmentThe steel billet is placed in the heating furnace for heating. The heating temperature needs to be precisely controlled according to the material and specification of the steel. Generally, it is heated to 1100-1250 ℃ to make the steel billet reach a red-hot state, which improves its plasticity and facilitates subsequent rolling processing.
- Rolling formingThe heated billets are sent to the rolling mill for rolling. The rolling process is usually divided into two stages: rough rolling and finish rolling.
- Rough rolling: Through several passes of rolling, the billet is gradually rolled into a prototype close to the shape of Angle steel, reducing its cross-sectional dimensions and increasing its length.Precision rolling: Further rolling of the prototype to make its size, shape and Angle meet the standard requirements of Angle steel, ensuring the accuracy and quality of the Angle steel.
- Cooling and straighteningThe Angle steel that has been rolled needs to be cooled, which can be achieved through natural cooling or forced cooling (such as water cooling). During the cooling process, Angle steel may undergo certain deformation. Therefore, it needs to be straightened by a straightening machine to ensure its straightness and verticality.
- Surface treatment and inspectionAccording to the usage requirements, surface treatments such as rust removal, galvanization and painting are carried out on the Angle steel to enhance its corrosion resistance and appearance quality. After the processing is completed, a comprehensive inspection is conducted on the dimensions, mechanical properties, surface quality, etc. of the Angle steel to ensure that the product meets relevant standards and customer requirements.
Advantages of Angle steel
- High structural strength
- The cross-section of Angle steel is right-angled. This structure endows it with high bending strength and rigidity in both directions, enabling it to withstand large loads and making it suitable for structures that need to bear complex stresses.
- Good stability
- Due to the symmetry of its cross-sectional shape, Angle steel is not prone to twisting or deformation under force and has good stability, which can be used to construct stable frame structures.
- Convenient for processing
- Angle steel can be conveniently processed by cutting, drilling, welding and other operations, and is easy to be customized and assembled according to the actual engineering requirements, which can greatly improve the construction efficiency.
- Wide application range
- It can be used in multiple fields such as steel structure frames in construction projects, bridge construction, brackets and support structures in mechanical manufacturing, towers and brackets in power engineering, shipbuilding, and the manufacturing of various industrial equipment.
- Good economy
- The production process of Angle steel is relatively mature, with a low production cost and a high cost performance. Under the premise of meeting the engineering strength and usage requirements, it can save costs for the project.
- Diverse varieties and specifications
- There are various side lengths, thicknesses and materials to choose from. Users can select the appropriate Angle steel specifications based on specific usage scenarios and requirements, offering high flexibility.
