Ductile iron roll

Ductile iron roll is a kind of roll made by spheroidizing molten iron with magnesium and pouring it into the cold or cold mold of the sand lining. Due to the spheroidization treatment, the graphite carbon inside the cast iron changes from flake to spherical, which eliminates the stress concentration of graphite tip caused by flake graphite, and makes the strength of cast iron significantly improved, and the strength is similar to that of cast steel rolls, but the wear resistance is much higher than that of cast steel rolls. At present, there are three kinds of nodularizing agents used: magnesium, cerium and calcium, among which magnesium is more common as a nodularizing agent. Ductile iron rolls can be used in billet mills, roughing mills and mills before finishing rolling for various sections and plates. Finished rolls can also be used when the load is not large. When the finished roll bears a large load, it is best to use ductile iron cold-hard rolls with casting grooves, high strength and good wear resistance.
