Working rolls are the core functional components of cassette-style levelling equipment and determine the overall levelling accuracy and finished surface quality of metal strips. Our high-performance leveling cassette working rolls are professionally engineered for modern strip processing lines, delivering outstanding flatness correction and flawless surface finishing for a wide range of metal strip materials.
We produce high-precision working rolls in standard industrial specifications, covering mainstream diameters of Ø30mm, Ø45mm and Ø70mm. The standardized dimension range is compatible with most common levelling cassette structures and equipment models on the market, achieving perfect matching and versatile applicability for diverse industrial levelling scenarios.
1.Key Features & Product Advantages of Leveling Cassette Working Rolls
- Premium Material & High Hardness Property: Our working rolls are fabricated from high-purity alloy steel and premium-grade tool steel. Through professional and standardized heat treatment procedures, the rolls achieve a stable surface hardness of HRC 58-62+ with a deep, uniform hardened layer. The optimized material structure provides excellent wear resistance and anti-indentation capability during long-term continuous levelling operation.
- Micron Precision & Mirror Surface Finish: Adopting ultra-precision cylindrical grinding technology, each working roll is processed to strict micron-level tolerance, ensuring excellent cylindricity, coaxiality and ultra-smooth mirror surface. The high-precision finishing effectively avoids surface scratches, indentations and marking defects on sensitive materials including aluminum, copper and polished stainless steel strips.
- Excellent Load-Bearing & Structural Stability: Tailored for high-pressure tension levelling working conditions, our working rolls feature optimized mechanical structure design. They can stably withstand continuous high specific pressure and heavy loads, maintaining complete structural integrity and geometric accuracy during long-term high-speed operation, thus ensuring stable and uniform levelling results.
- Extended Operational Lifespan: The perfect combination of superior raw materials, professional heat treatment and high-precision grinding greatly improves the fatigue resistance and comprehensive durability of the rolls. It effectively prolongs the service cycle, reduces frequent roll replacement and equipment downtime, and helps enterprises lower overall production and maintenance costs.
- High Interchangeability & Stable Reliability: Supported by strict full-process quality inspection and dimensional calibration, all working rolls feature accurate overall dimensions and standard assembly tolerances. They are fully interchangeable with original standard levelling cassettes, realizing quick installation, zero debugging and stable long-term operational performance.
