China Skin Pass Mill Suppliers and Factory for High-Quality CR Strip Coil Processing Equipment

MAIN FUNCTION OF THE EQUIPMENT

The primary function of our advanced machinery is to effectively flatten cold rolled (CR) strip coils. By applying a small reduction rate during the process, these coils experience a reduction in internal stress and yield point elongation, ensuring that slip lines do not form during subsequent stretching and punching operations.

Following the annealing process, the CR coil strip undergoes tempering, significantly enhancing both the flatness and surface finish of the coils. This ensures higher quality for end applications.

Furthermore, by fine-tuning the reduction rate during tempering, we can achieve a specific range of mechanical properties in the coil strip. This versatility allows us to tailor the hardness and plasticity to meet a variety of functional requirements.
