Taking Account of the Stress–Strain State of High-Strength Steel Strip in Determining the Normal Contact Stress Distribution over the Deformation Zones in Hot Rolling

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.
