Product Description Product DescriptionBrief Introduction of HSS Roll The HSS roll material contains high contents of alloying elements such as Vanadium (V), Chromium (Cr), Tungsten (W), Molybdenum (Mo), and Niobium (Nb). The dominant carbide type is MC, which features high hardness and excellent wear resistance.HSS rolls exhibit good thermal stability. During hot rolling, the roll surface maintains high hardness and excellent wear resistance.HSS rolls offer good hardenability, with minimal hardness drop from the surface to the scrap diameter, ensuring consistent wear resistance throughout the working layer.

Material CharacteristicsSlitting 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 Slitting Stands ? High hardness and wear resistance ? Excellent thermal fatigue resistance ? Long service life, fewer roll changes ? Enhances surface finish of rolled products ? Stable under high-speed rolling conditions ? Optimized alloy composition with precise heat treatment4.Application: ? Used in hot rolling of bar, wire rod, and section steel ? Ideal for high-speed continuous rolling lines ? Suitable for finishing stands and pre-finishing stands ? Applied in modern steel mills and rolling workshops Detailed Photos Company ProfileAnhui Huanbowan High Speed Steel Mill Roll Co., LTD Anhui Huanbowan High Speed Steel Mill Roll Co., LTDAnhui Huanbowan High Speed Steel Mill Roll Co., Ltd. was established in 2007 (formerly Beijing Huanbowan), and is a professional manufacturer specializing in high-performance high-speed steel (HSS) mill rolls and roll rings.In 2014, the company relocated to Tongling City, known as the "Bronze Capital of China," and expanded its production capacity to 15,000 tons per year.
