1. Material Characteristics
Slitting high-speed steel rolls are made from HBW patented high-speed steel containing high-alloy elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr). Key characteristics include:
• High Hardness and Red Hardness: Maintains surface hardness of HSD73-78 or above even under high-temperature conditions.
• Excellent Wear Resistance: The hard particles and refined grain structure of high-speed steel significantly enhance wear resistance.
• Thermal Fatigue Resistance: Adapts to high-temperature and thermal cycling environments, reducing the risk of surface cracking and spalling.
• Good Toughness: Sufficient strength and toughness to withstand high loads and impacts during rolling.
2. Key Performance Features
• Wear Resistance: Performs well under high-speed and heavy-load conditions, ensuring a long service life.
• Thermal Stability: Maintains dimensional stability and efficient performance even at temperatures of 900-1050°C.
• High Precision: High machining accuracy ensures consistent dimensions during multi-line slitting rolling.
• Low Replacement Frequency: Reduces downtime and increases production efficiency.
3. Advantages of HSS Rolls for Dogbone Stands
• Durability: The ability to withstand high temperatures and pressures extends the life of the roll, making it more cost-effective over time.
• Precision: HSS rolls help ensure that the dogbone profiles produced meet exact specifications in terms of dimensions and surface finish.
• Energy Efficiency: The durability and resistance to wear allow for a more stable and efficient production process, reducing the need for frequent replacements and downtime.
