Product Description Product Description Brief Introduction of HSS RollHigh-speed steel (HSS) rolls are advanced metallurgical products widely used in the modern steel industry for hot rolling applications. These rolls are known for their exceptional wear resistance, high-temperature hardness, and thermal fatigue resistance. Composed of alloy elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr), HSS rolls exhibit superior durability and performance compared to traditional cast iron and cast steel rolls. By adopting high-speed steel rolls, steel manufacturers can achieve improved efficiency, lower maintenance costs, and superior product quality.Detailed PhotosProduct ParametersPhysical Parameter NormalEnhancedHigh StrengthSlitting DogboneRoll Specification ?280 - ?850Density7.6 g/cm37.8 g/cm38 g/cm37.6 g/cm37.6 g/cm3Casting Centrifugal CastingHeat Treatment HBW Patented Hardness General: 82-89HSD Different range based on stands73-77HSD73-77HSD79-83HSDHardness Drop≤3HSDRolling Temperature780oC-1100oC Pass Life4-5 times than CI Rolls1.3 tims thanHSS Normal 1.5 tims than HSS Normal 24-32 hours Continue Rolling (2-3 times than High-boron Rolls)Dressing1.0-1.5mmUse Periods8-10 CyclesApplicationIntermediate and Finishing stands in bar mill Fours stands before pre-finishing stands in wire mill Hot strip and plate steel working rolls Section steel universal mill Slitting standin bar millDogbone standin bar mill PropertiesBarrelCoreTensile Strength(N/mm2)≥700MPa≥450MPaCompressive Strength ≥2500MPa Chemical Analysis (Proportion differert based on HSS Grade) Material HBW Patented Chemical Composition (%)HSS NormalCSi Mn Cr Ni MoVWP & SNbCoOthers1.5-2.100.30-0.70.30~1.03.00~ 6.000.50~1.503.0-7.02.08.01.0-8.0≤0.03Depends on HSS GradeWe also have HSS Enhanced& HSS High Strength Grade Material!(Welcome Inquiry)Advantage of High-Speed Steel Rolls1. 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 hot rolling processes, excelling both in normal and low temperature rolling environments as well as meeting the stringent surface quality and dimensional accuracy standards.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 as the core, marrying wear resistance with impact toughness seamlessly.Applications 1. Hot Rolling: ? Used for rolling rebar, wire rods, bars, and plates. 2. Special Material Rolling: ?
