  • Spalling Prevention and Wear Improvement of Rolls in …

    Abstract. Rolls are key components in hot strip mill. Roll wear and fatigue are inevitable phenomena during hot-rolling process. Finite element (FE) analysis shows that roll profiles, especially work roll wear profile, have significant effects on contact stress distributions.


  • Analysis of thin strip profile by work roll crossing and ...

    The results show that the strip profile is nearly flat under asymmetrical rolling. The rolling force was also analyzed in detail by changing the crossing angle and axial shifting value of work rolls. The rolling force was also analyzed in detail by changing the crossing angle and axial shifting value of work rolls.

  • Improving Thin Strip Profile Using Work Roll Cross and ...

    The purpose of work roll crossing is to obtain a larger efficiency of shape and profile control by increasing the roll gap by increasing the distance from the roll center . By slightly crossing the upper and lower work rolls and reducing the roll force across the roll from the center to the edge of the strip, a bigger crown can also be achieved.
