Rolled Steel – Pinch Roll Vices
A prominent steel mill was experiencing performance issues associated with their hydraulic pinch roll vices, causing unplanned maintenance and lost production
The O-Ring energized rubber seals would compression set and begin leaking severely after only 1-week leading to product quality and scraping issues.
Replacement of the seals would stop rolled steel production and require 3 men and 6 hours to replace. Production is typically 1 roll/hour.
Chesterton recommended a 22KE piston sealing solution made from its proprietary high-temperature thermoset polymer.
- Chesterton® 22KE: Single-acting energized dual component seal for added stability, integrating a FKM O-ring loader
- Chesterton® AWC 860: Thermoset wear resistance material with ability to seal up to 120° C (250° F)
SpeedSeal: Chesterton’s regional manufacturing center for made-to-order product to fit original hardware with quick delivery.
Improved Performance & Reliability
Chesterton replaced 10 seals which have been operating leak-free for 4 ½ months to date. This solution has eliminated leakage and quality issues of the vices, as well lost profits associated with scrapped product.
- Savings: 1 roll of inox steel = €50,000
- MTBR increased: 18X and counting
