High strength ductile iron roll

High strength ductile iron rolling mill is one of the special rolling mills produced by Dongye Company. We have changed the chemical composition of ordinary SG rollers and modified the heat treatment method. The tensile strength of the rollers can reach 600MPa. Due to its high strength, this type of roller can replace alloy cast steel rollers and diamond rollers. The wear performance is better than that of two rollers. High strength ductile iron rolling rolls have high strength, good thermal performance, and the ability to resist emergency situations, with a small hardness gradient in the working layer.
