Plunger Roller or rolls for mill mahcine 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.
The advantages for Plunger Roller:
Reduces journal breaking problems.
Better thermal conductivity as in the rolls are completely machined from inside also.
Better wear resistance.
Plunger Roller Features:
1. Precision engineering
2. Impeccable design
3. High performance
Materials for Plunger Roller:
Smooth Rolls For Reduction / Polish Passages
OCC® 460 Matt
Fluted Rolls for Break Passages
OCE® 600 Ultra
OCC ® 460 Matt Plunger Rollers are special rolls for reduction stages of grain. This special material also helps in reducing your power consumption up to 18%.
OCE ® 600 Ultra Plunger Rollers are special rolls used for breaking or cracking of different grains, etc. This special material also helps in increasing the life of the fluted rolls for mill mahcine up to 40%.
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.
