The Scale Breaking work roll is a high-performance roll designed for hot rolling mills, specifically engineered to enhance descaling efficiency and improve strip surface quality. By effectively breaking and removing oxide scales (mill scale) from the surface of hot metal slabs or billets, this roll ensures smoother subsequent rolling processes, reduces defects, and extends the lifespan of downstream equipment.  

Key Features:  

1. Superior Descaling Performance  

   - Utilizes advanced groove designs and hardened materials to fracture and detach stubborn oxide scales with minimal energy consumption.  

   - Reduces scale-related surface defects (e.g., pitting, scratches) on finished products.  

2. Robust Durability  

   - Manufactured from high-chromium alloys or composite materials with exceptional heat resistance and wear properties.  

   - Withstands extreme temperatures (up to 1,200°C) and mechanical stress in continuous rolling operations.  

3. Optimized Roll Profile  

   - Precision-engineered grooves or textured surfaces maximize scale-breaking efficiency while minimizing roll wear.  

   - Customizable designs to match specific mill configurations and material grades (e.g., carbon steel, stainless steel).  

4. Low Maintenance & Cost-Effective  

   - Extended service life reduces downtime for roll replacements.  

   - Compatible with standard roll grinding and refurbishment processes.  

Applications:  

- Hot Strip Mills (HSM): Installed in the roughing or finishing stands to pre-treat slabs before final rolling.  

- Plate Mills: Ensures uniform scale removal for heavy plates.  

- Specialty Alloy Processing: Effective for high-temperature alloys prone to tenacious oxide layers.  

Benefits:  

✔ Improves surface quality of rolled products.  

✔ Enhances rolling efficiency by reducing scale-induced roll wear.  

✔ Lowers operational costs through reduced scrap rates and energy savings.
