Product Description
Hot-rolled High Speed Steel Roll
High-speed steel rolls are high-performance rolls used in the metallurgical rolling industry.
They are widely applied in hot rolling processes, especially for rolling high-strength steel, stainless steel, and other difficult-to-process materials.These rolls are made from high-speed steel (HSS), a type of high-alloy tool steel containing elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr), which endow the rolls with exceptional performance.

Our Advantages
Advantage of High-Speed Steel Rolls
1. High Wear Resistance
• Crafted with a generous blend of hard carbides such as tungsten, vanadium, and chromium, these HSS rolls offer unmatched wear resistance, making them a top choice for challenging rolling tasks.
• Perfectly designed for the rigors of rolling high-strength steel, stainless steel, and other demanding materials, ensuring exceptional performance.
2. High Hardness
• Achieving a working layer hardness of 65 HRC or higher, these rolls are engineered to maintain their formidable hardness even when subjected to intense high-temperature conditions.
• A consistently uniform hardness distribution effectively prolongs the service life of the roll, offering enduring reliability.
3. Excellent Thermal Crack Resistance
• Engineered to withstand high-temperature rolling scenarios, the surface is resilient against cracking caused by rapid cooling or thermal stress challenges.
• Exceptionally suited for continuous operations in high-temperature and high-stress settings, showcasing unparalleled durability.
4. Thermal Fatigue Resistance
• With outstanding resistance to thermal fatigue, these rolls deliver stable performance across repeated cycles of heating and cooling, minimizing fatigue crack development.
5. Long Service Life
• Boasting a lifespan 3-6 times greater than traditional cast iron or cast steel rolls, HSS rolls significantly cut down on replacement frequency and downtime, enhancing operational efficiency.
6. Strong Versatility
• Versatile enough for both hot and cold rolling processes, excelling in high-temperature, high-pressure environments as well as meeting the stringent surface quality and dimensional accuracy standards in cold rolling.
7. Advanced Manufacturing Technology
• Produced using state-of-the-art centrifugal composite casting technology, these rolls feature HSS as the robust working layer with ductile cast iron or forged steel as the core, marrying wear resistance with impact toughness seamlessly.
