It is produced by adding magnesium 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.
