Quench Wringer Rolls
Quench Wringer Rolls
Universal Urethane manufactures urethane quench wringer rolls designed to remove excess quench fluids, coolants, and process oils from strip and sheet surfaces in continuous processing lines. Built for high-temperature, high-pressure nip applications, our urethane-covered quench rolls deliver uniform squeezing action, excellent chemical resistance, and non-marring contact to ensure clean, dry, and defect-free metal surfaces.
Core Construction
The reliability of a quench wringer roll starts with its core, which must endure thermal cycling and high nip loads while maintaining concentricity and balance.
- Core Materials: Heavy-duty steel, stainless steel, or aluminum construction engineered for dimensional stability under elevated temperatures.
- Precision Machining: Journals and bearing seats machined or reground to OEM tolerances for accurate fit and dependable alignment under load.
- Journal & Shaft Services: Core restoration, shaft replacement, weld repair, and press-fit operations extend roll service life and maintain proper bearing engagement.
- Dynamic Balancing: All rolls dynamically balanced after machining and recovering to minimize vibration and ensure smooth operation at line speeds.
- Complete Assemblies: Supplied fully assembled with shafts, bearings, couplings, and urethane coverings for direct installation and startup.
Urethane Covering
The urethane cover is formulated to perform under hot, wet, and chemically aggressive conditions typical of quench and rinse lines.
- Durometer Range: Custom polyurethane hardness from 80–95 Shore A selected for consistent nip pressure, minimal deformation, and extended wear life.
- Surface Finish: Precision-ground smooth finishes ensure uniform pressure distribution and non-marring contact with coated or polished strip surfaces.
- Grooved Options: Helical, herringbone, or spiral grooves available to enhance fluid displacement, reduce hydroplaning, and improve drainage efficiency.
- Performance Properties: Exceptional tear strength, high temperature stability, and resistance to oils, coolants, acids, and alkaline cleaning solutions.
- Bonding & Cure: Urethane covers applied using grit-blasted cores, high-performance primers, and heat-cure processes to achieve maximum bond integrity under thermal cycling.
Performance in Coil Processing
Quench wringer rolls are designed for precise, consistent operation in demanding coil processing environments.
- Apply uniform nip pressure to remove quench fluids and oils effectively.
- Maintain non-marking contact to protect sensitive or coated strip surfaces.
- Deliver stable traction and fluid control in hot, wet, or chemical-exposed conditions.
- Resist wear, thermal fatigue, and deformation through repeated heating and cooling cycles.
Maintenance & Recovering Services
Universal Urethane supports full-service rebuilding and recovering to extend roll life and minimize downtime.
- Recovering: Existing rolls stripped, inspected, refurbished, and re-covered with new urethane formulated for high-temperature quench applications.
- Rebuild Process: Includes cleaning, NDT inspection, shaft repair, precision grinding, dynamic balancing, and finishing to original specifications.
- Service Options: Standard and expedited turnaround available with pickup and delivery to keep production on schedule.
Applications
- Quench and rinse lines in steel and aluminum coil processing
