Plastic deformation during forming: During the forming process of the square tube in the rolling mill, due to the use of continuous rolling as a manufacturing process, the microstructure of the metal can be effectively improved, so that the metal grains are evenly distributed. This uniform metal structure helps to improve the toughness of the material.
2. Uniform stress distribution
Excellent process parameter control: During the rolling process, due to its special forming process, stress concentration can be effectively controlled to avoid the occurrence of sharp stress concentration points. This uniformly distributed stress helps to improve the impact resistance and toughness of the square tube and reduce the risk of brittle fracture.
3. Higher weldability
Excellent welding performance after forming: The rolling process of the square tube can improve its welding performance and make the toughness of the welded joint better. Good welding toughness makes it less likely for the square tube to crack or break when subjected to dynamic loads and impacts.
4. Reasonable wall thickness
Optimized design and control: The design of the square tube formed by the rolling mill usually takes into account the rationality of the wall thickness. The wall thickness is uniform and appropriate to ensure that it can effectively disperse the force and enhance its toughness when subjected to external impact and load.
5. Reduce defects and residual stress
Precise control of the forming process: Compared with other scrap processing or casting processes, rolling reduces the defects inside the material (such as pores, inclusions, etc.) to a certain extent, and can effectively reduce the residual stress in the material, thereby showing better toughness in use.
6. Excellent energy absorption characteristics
Good plastic deformation ability: The braiding and toughness of the square tube enable it to effectively absorb energy when it is impacted or collided, avoiding sudden fracture. This feature is particularly important in applications such as construction and automobile structures.
7. Flexibility of the heat treatment process
Subsequent heat treatment to improve toughness: The square tube can be subjected to heat treatment processes such as annealing after rolling. Reasonable heat treatment can further improve its plasticity and toughness and enhance the comprehensive performance of the material.
8. Fatigue resistance
Good fatigue resistance: Due to the good toughness of the square tube, it shows excellent fatigue resistance under cyclic loads, which is very important for the application of structural parts in dynamic working environments.
In general, the square tube of Used Directly Forming To Square Pipe Mill ensures its excellent performance in toughness through uniform metal structure, uniform stress distribution, good welding performance, reasonable wall thickness, reduced defects and residual stress, superior energy absorption characteristics, flexibility of subsequent heat treatment and good fatigue resistance. This makes square tubes widely used in many industries (such as construction, machinery, automobiles, etc.) and can withstand a variety of complex working environments.
