CAST ROLLS FOR HOT ROLLING MILLS
Cast rolls are one of the core parts of steel rolling mills. They refer to the roll parts made through casting process and used in rolling mills to achieve the deformation of metal billets. They are widely applied in various steel rolling production lines such as section mills, bar mills, hot strip mills and plate mills.

- Pearlitic Ductile Cast Iron Rolls
- Bainite Ductile Cast Iron Rolls
- Alloy Indefinite Chilled Cast Iron Rolls
Features
of cast Rolls
The cast rolls, as the core wear-prone components of the steel rolling production line, directly determine the operation efficiency of the rolling mill, the quality of the rolled materials, and the production cost. During use, they must meet two major core requirements: mechanical properties and usage performance.
Mechanical properties requirements:
- High wear resistance
- Sufficient strength and toughness
Excellent anti-thermal fatigue performance
Key usage performance requirements:
- Good anti-adhesion property (anti-rail surface scabbing)
- Dimensional stability and shape accuracy
- Corrosion resistance (for specific working conditions)
