Spheroidal Graphite Steel Rolls

We are a respectable Manufacturer and Supplier of Spheroidal Graphite Steel Rolls. Spheroidal Graphite Iron Rolls (S G Iron) is considered as one of the most versatile roll materials now a days. Spheroidal Graphite Steel Rolls are produced by a small proportion of magnesium added to the melt as nickel-magnesium or alternative alloy, or as pure magnesium. In Spheroidal Graphite Steel Rolls, the free carbon takes the shape of spheroids or nodules thereby eliminating the notch effect of flake graphite and improving upon the mechanical properties of the cast iron. In these Spheroidal Graphite Steel Rolls, the graphite is in the form of spheroids produced by suitable inoculation. Most nodular iron rolls are chill cast resulting with a hard working layer and softer nects. The alloy content is accurately controlled to give fine and well distributed graphite nodules and refined carbide in generally pearlitic or beinitic / martenstic matrix. The higher alloy content Cr-Ni-Mo makes the Spheroidal Graphite Steel Rolls tougher & wear resistant.
