Introduction
Hot rolled groove steel is a kind of cold formed product formed by hot rolling process, which is widely used in the production of some sheet metal parts, chassis and frame parts, etc. Its products are generally shaped in the form of U-steel, C-steel, hats and other types of steel. Hot rolled groove steel due to its good process performance, welding performance and structural performance is widely used in automobiles, freight cars, tractors and other engineering vehicles.
Characteristics of Hot Rolled Groove Steel
1. The minimum dimensions of hot rolled groove steel products are usually determined by the rolling equipment and the rolling process. Generally, the length of the product reaches 6mm, which can meet the design requirements of the automobile sheet metal parts.
2. The section size of the hot rolled groove steel is the same as the original material before rolling. That is to say, the allowable deviation of the grooved steel section size is small, and the material consumption is reduced and the cost is low.
3.The forming process of hot rolled grooved steel is simple, which can save mold cost, reduce the difficulty of production process and improve efficiency.
4.Hot rolled groove steel has good rigidity and plasticity and good weldability, which makes it a good mechanical structure material.
5. The surface of the hot rolled groove steel has smooth appearance and precise size, so it is beautiful and easy to form the product.
6. Hot rolled groove steel has good welding performance. After welding with other structural parts, it can form a rigid whole and strengthen the structural stability of the product.
Applications of Hot Rolled Groove Steel
Hot rolled groove steel can be widely used in automobiles, building structures, bridges and other fields. Generally, the commonly used groove steels can be divided into four categories: steel beams, box beams, purlins and steel plates.
1. Hot-rolled groove steel is often used in the manufacture of automobile frames, body frames, chassis and other automotive components.
2. Box beams are often used in the manufacture of large steel structures, such as port structures, petrochemical plants and oil refineries.
3. Hot rolled groove steel is often used in the manufacture of prefabricated houses, such as light steel structures, color steel structures, steel structure buildings and so on.
4. In general, hot rolled groove steel is also applied to bridges, shipbuilding and other fields.
Conclusion
In conclusion, hot rolled groove steel is a kind of cold formed product formed by hot rolling process, which has good process performance, welding performance and structural performance. It can be widely used in automobiles, buildings, bridges and other fields, and has a wide range of applications.
