Alloy cast steel rolls for roughing mills 70II are a common roll material made of steel containing alloying elements that improve the hardness, wear resistance, and corrosion resistance of the rolls. The alloy cast steel roll has good wear resistance and can withstand the friction and wear of the metal billet during high-speed rolling, extending the service life of the roll. The 70II rollers have high hardness and can withstand large rolling pressure and impact load, ensuring the stability and safety of the rolling process. Compared with some more expensive roll materials, alloy cast steel rolls have lower manufacturing costs, but their performance can still meet the requirements of roughing mills. They are suitable for various roughing mills and can meet the rolling needs of metal billets of different sizes and materials. need.
