Compared with traditional ductile iron roll and high Ni-Cr roll, high-speed steel roll has higher wear resistance and higher single-pass over-steel volume, saving the roll change time, improving mill operating rate, reducing roll consumption and reducing Production costs, improve the overall efficiency of the factory.

General one groove carrying capacity is 3 to 5 times than nickel-chromium roll. The following table is the use of high speed steel roller and bainitic ductile iron bar in the bar machine on the effectiveness of the comparison.
