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
Please take note of our roll material overview and material recommendations on the right.
