Principle of roll forming process
- Roll forming relies on pairs of rolls in continuous arrangement.
- The roller set has a specific shape and profile.
- After the metal plate enters, the roller set applies pressure and friction to deform it.
- The change brought by a single roll group is small, and the change accumulates after multiple roll groups.
- Deformation can be controlled through precise design and adjustment of roll set parameters to transform the sheet into a specific shape.
- The fluidity and ductility of the metal are used for efficient and precise molding, and continuity ensures a wide range of applications.
The formation of complex contours
- It begins with the metal plate entering a continuous roll set.
- Small deformation is applied to each roll group in sequence.
- Small deformation accumulation and superposition.
- The deformation direction is guided by precisely adjusting the parameters of the roll group.
- Eventually, complex contours are formed.
Advantages of roll forming process
- Continuous operation, high efficiency.
- Low cost, high material utilization.
- The product has high precision and good consistency.
- ADAPTS to a variety of materials.
- Complex shapes can be formed.
Application of roll forming process in steel mills
Production of steel: such as I-steel, channel steel, etc. In steel mills, the section steel produced by roll forming is widely used in building structures. For example, in the construction of large Bridges, high-quality rolled I-beams ensure the stability and load-bearing capacity of the bridge and are a key support material for the entire project.
