Hydraulic cylinder of flipping machine

Hydraulic Cylinder for Coil Turning Machine: Features & Functions

Key Features:

1. Heavy-Duty Construction

   • Reinforced steel body withstands 200-500T dynamic loads

   • Hard-chrome plated rods (≥25μm) resist abrasive scale particles

2. Precision Movement

   • Integrated position sensors enable ±1mm flip accuracy

   • Cushioned end-stops prevent coil edge damage

3. Specialized Configurations

   • Dual-rod design for balanced force distribution

   • High-temperature seals (FKM material) for hot coil handling (up to 250°C)

4. Environmental Resistance

   • IP67 protection against coolant/oxide dust

   • Corrosion-resistant coatings for humid mill environments

Core Functions:

• Safe Coil Rotation
  Performs 90°/180° flipping of 20-50T steel coils between processes

• Process Optimization
  Enables transition between horizontal/vertical coil positions for:
  • Pickling line entry
  • Cold mill feeding
  • Downcoiler discharge

• Operational Safety
  Emergency retract function prevents coil drops
  Load-holding valves maintain position during power loss

Technical Standards:
Complies with ISO 6020/2 (metric series) and ASTM A519 (tube material)

Industry Applications:
Hot/Cold rolling mills
Steel service centers
Non-ferrous metal processing
