    • Metallographic Structure

    The metallurgical structure of roll-body work layer is: Pearlite + carbide or fine pearlite + a little bainite + carbide

    Specifications

    1.Alloy Indefinite Chilled
    2.Small hardness gradient
    3.Suit to medium and finish stand for bar, wire
    4.For bar and rod mills


    Alloy indefinite chilled cast iron roll is a cast iron with fine intercrystalline graphite evenly distributed throughout the working layer of roll barrel. The sizes, shapes and distributions of graphite and carbide are controlled by the chilling effect and the contents of alloy elements. The addition of alloy elements such as manganese, nickel, chromium, and molybdenum chages the matrix microstructure from pearlite, bainite to martensite.


    This roll has small hardness gradient in the working layer of roll barrel and is suitable to medium and finishing stands for bar, wire and section mills.
