The influence of the leveler rolls, tension, and shear accuracy of a cut-to-length machine on the finished strip shape.
A cut-to-length line consists of uncoiling, leveling, fixed-length shearing, and stacking.
Selection considerations:
- The range of strip thickness and width that can be processed.
- The number and diameter of leveling rolls (more rolls and smaller diameters are more advantageous for thin strip).
- Fixed-length accuracy and shear burr control.
- Tension control method (affects strip shape and scratching).
Strip shape control: The incoming strip shape is the foundation; leveling parameters must be adjusted according to the material's yield strength; thin strip is prone to waviness, so tension and roll gap need to be controlled.
