Key Points

  • This research aims to assess how normal contact stress affects the durability of rolls in hot-rolling mills.
  • Analyzed normal contact stress in the finishing stand of hot rolling mills.
  • Evaluated rolling conditions and tensions between the stands.
  • Proposed modifications to reduce contact stress levels.
  • Contact stress measured between 1100–1230 MPa under standard conditions.
  • Proposed adjustments could decrease stress to 802 MPa, potentially extending roll life.

Abstract

The influence of normal contact stress on the durability of rolls in the finishing stand of a hot-rolling mill is considered. In the given rolling conditions, contact stress of 1100–1230 MPa appears in the finishing stand. Changes in the rolling conditions and the tension between the stands is suggested so as to reduce the contact stress to 802 MPa and extend roll life.
