Slitting Line (also known as Slitter or Longitudinal Shear Line) is a production line that longitudinally slits wide steel coils (such as hot-rolled steel strips, cold-rolled steel strips, etc.) into multiple narrow strips of required widths. It is an essential cutting device in the steel processing industry.
Main Functions:
· Slit wide coils into multiple narrow steel coils of specific widths
· Ensure smooth, burr-free slit edges
· Recoil each narrow steel strip separately
· Adapt to different thicknesses, widths, and material types of steel strips
Main Process Flow:
1. Uncoiling: Load the raw steel coil onto the uncoiler
2. Leveling: Steel strip passes through a leveler to eliminate internal stress
3. Slitting: Steel strip is longitudinally cut by pairs of circular slitter blades
4. Scrap Winding: Edge trims are collected by scrap winders
5. Tension Control: Provides stable back tension to ensure slitting quality
6. Recoiling: Each narrow steel strip is recoiled into s…
