High-Speed Steel Coil Slitting Line Manufacturer | AIS MACHINERY

Equipment Composition

A typical AIS MACHINERY high-speed slitting line includes the following main components:

1. Hydraulic Uncoiler – Holds and uncoils heavy steel coils (up to 25 tons).

2. Leveling Unit – Flattens the coil to ensure uniformity before slitting.

3. Slitter Head – Equipped with rotary knives to cut the coil into multiple strips.

4. Scrap Winder – Rewinds edge scrap for easy collection.

5. Tension Stand – Applies back tension for clean rewinding.

6. Recoiler – Rewinds the slit strips into compact coils.

7. Hydraulic Pusher & Coil Car – For easy loading/unloading of master and slit coils.

8. PLC Control System – Centralized touchscreen interface for automated and manual operation.

Operating Process & Step-by-Step Explanation

1. Loading the Coil
   The coil is loaded onto the hydraulic uncoiler using a coil car. Hydraulic arms clamp the coil securely.

2. Feeding & Leveling
   The steel sheet is fed into the leveler to remove curvature and ensure flatness.

3. Slitting Process
   The sheet enters the slitter, where rotary knives precisely cut it into pre-set strip widths.

4. Edge Trimming & Scrap Collection
   Scrap edges are removed and wound by the scrap winder.

5. Tension Control
   The strips pass through the tension stand to ensure tight, even rewinding.

6. Recoiling
   Each slit strip is wound into a coil on the recoiler. A separator system ensures neat stacking.

7. Unloading
   Finished coils are pushed out with a hydraulic pusher and moved via coil car.

Applications of Slit Steel Strips

The slit strips produced by our machines are widely used in:

• Tube and Pipe Manufacturing
  Especially for ERW straight seam welded pipes.

• Cold Roll Forming Lines
  Used as feedstock for producing C/U/Z purlins, door frames, etc.

• Stamping and Pressing
  For automotive, white goods, and hardware components.

• Cable Tray and Rack Systems

• Metal Roofing and Panel Production

Precision Manufacturing & Quality Assurance

• CNC Machining for Accuracy
  All critical components, including knife shafts and spacers, are machined using high-precision CNC centers to ensure tight tolerances and minimal vibration.

• High-Quality Bearings and Drives
  We use top-brand bearings and gearboxes to guarantee durability and stable operation.

• In-House Quality Control
  Each machine undergoes strict dimensional inspection, trial operation, and functional testing before delivery.

• ISO and CE Standards
  Our slitting lines comply with international standards to ensure safety and performance.
