DOROLLER Iron Rolls or Plunger Roller or Spheroidal Graphite Iron Rolls is considered as one of the most versatile roll material. It is produced by a small propostion of magnesium added to the melt as nickel-magnesium or alternative alloy, or pure magnesium. In DOROLLER Iron roll, the free carbon takes the shape of spheroids or nodules, thereby eliminating the notch effect to flake graphite and imporving upon the mechanical properties of cast iron.
Plunger Roller Features:
1. Precision engineering
2. Impeccable design
3. High performance
DOROLLER Plunger Roller or Iron rolls find application in Roughing and Intermediate mills for rail and structural mills as well as in finishing mills for wire rod and narrow strip mills.
