Home Rolling Mill Rolls Centrifugal and Static Casting Spheroidal Graphite(SG) Acicular Cast Iron Roll and Ring
Centrifugal and Static Casting Spheroidal Graphite(SG) Acicular Structure with Non Continuous Carbide Cast Iron Roll and Ring for Rolling Mill

alt Properties

Improve in wear resistance and thermal fatigue resistance. High fracture toughness reduces the degree of fire cracking and helps to extend the campaign time. The high strength spheroidal graphite core overcomes the high loads.
