  • Hot Strip Millan overview ScienceDirect Topics

    Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well but under pressure with elastic deformation the friction is much less except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill). The wear is uneven from one end of the barrel to the other.

  • Rolling (metalworking)Wikipedia

    Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing they recrystallize which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal like semi-finished casting products such as slabs blooms and billets.
