Sink Roll Sleeve

Continuous galvanizing line(CGL)
Continuous galvanizing line
Sink Roll

Sink Roll:
Work in high-temperature molten metal environments

(Zn at 480℃, Al at 680℃)
  • Subject to severe corrosion and erosion
  • Sink roll:
    Re-use through repair processes such as welding and hard facing
  • Sleeve and Bush:
    Replaced with new components
Advanced Material Development Strategy
  • 1) Concept design for material development considering process characteristics
  • 2) Development of material specialized in heat resistance and corrosion resistance
  • 3) Alloy powder production using gas atomization
  • 4) Application of Special Heat Treatment to overcome the limitations of sintered materials and achieve defect-free materials
  • 5) Design of bi-metallic material considering the area of use
  • 6) Production of bi-metallic material through canning and bonding process
Improved material properties, cost efficiency, and optimized utilization
