Rolls for hot strip and heavy steel plates

Work rolls, backup rolls and edger rolls for hot strip, heavy plate and sheet rolling mills

The properties for work rolls, backup rolls and edger rolls for the production of hot strip, heavy plates and thin sheets have to be adapted to the specific demands of the rolling mill.
The following roll conditions and roll properties have to be taken into consideration:

Stands with deep passes and high thermal and mechanical demands:

  • good thermal conductivity
  • high temperature strength
  • suitable gripping capability
  • sufficient tensile strength in the journal- and core material

Stands in which a true to size band or sheet with good surface quality can be produced:

  • high surface hardness with a low hardness reduction when using a decreasing roll diameter
  • high wear resistance
  • fire-crack resistance
  • dismantling-stability
