Pearlitic Nodular Cast Iron roll
Equipped with one of the best Pearlic Nodalar Cast Iron Rolls brands. Roll Group is one of the competitive manufacturers and suppliers of SGP rolls in China. Welcome to our website. Pearlic nodular cast iron rolls (SGP) are made by adding alloy elements such as Ni, Cr, Mo to ductile iron and undergoing special heat treatment. Pearlite ball roller has the characteristics of high strength, good thermal performance, strong resistance to sudden changes, and small hardness gradient in the working layer. Based on your requirements for the hardness of the rolling mill rolls, we will recommend the most suitable roll materials to ensure the correct grinding amount of the rolling mill rolls or to remove inventory.
