Slitting high-speed steel rolls are made from 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.
• 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.
Slitting HSS rolls are widely used in the following scenarios:
• Bar Split Rolling: Used for multi-line rolling of high-strength bars to enhance production efficiency.
• Wire Rod Split Rolling: Ensures consistent product surface quality and dimensional accuracy in high-speed wire rod production.
• Special Steel Rolling: Suitable for processing challenging materials like high-alloy steel and stainless steel.
