1. Material CharacteristicsAngle steel high-speed steel rolls are made from high-speed steel containing high-alloy elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr). Their characteristics include:
• High Hardness: Surface hardness can reach HSD82-89 or higher after specialized heat treatment, meeting the demands of high-strength rolling.
• Excellent Wear Resistance: Significantly extends roll service life and reduces replacement frequency.
• High Red Hardness: Maintains stable performance even under high-temperature conditions.
• Thermal Fatigue Resistance: Withstands thermal cycling, preventing thermal cracks and surface spalling.2. Performance Features • Wear Resistance: Suitable for continuous production under high-load conditions, extending roll lifespan.
• Thermal Stability: Maintains dimensional accuracy and shape stability in the high-temperature environment of angle steel rolling.
• Impact Resistance: Handles the alternating loads and impacts during angle steel rolling.
• High Precision Rolling: Ensures dimensional consistency and accurate cross-sectional shapes of angle steel.3. Applicationspiercing mills, reducing mills, and sizing mills, ensuring extended roll life and excellent surface quality of the final pipe products4. Technical Advantages • Increased Production Efficiency: High wear resistance and hardness reduce downtime, enhancing continuous production efficiency.
• Lower Production Costs: Longer service life reduces roll replacement frequency and maintenance costs.
• Improved Product Quality: Ensures smooth surface finish, precise dimensions, and complete cross-sectional shapes of angle steel products. Detailed Photos
