Product Description

 

Product Description

Brief Introduction of HSS Roll 



HBW HSS Roll (High-Speed Steel Roll) is a high-performance rolling mill roll made from high-speed tool steel through advanced metallurgical techniques. It is widely used in the rolling of hot strip, wire rods, and small-section steel. Compared to conventional roll materials such as alloy cast iron and alloy steel, HSS rolls offer superior wear resistance, thermal stability, and resistance to thermal fatigue, significantly improving mill productivity and rolled product quality.

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 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 treatment

4.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
