Adamite Rollers 160I (AD160I) can withstand the friction and wear of the metal blank during high-speed rolling, extending the service life of the roll. Semi-steel rolls are composed of a steel core and a cast iron outer layer. The steel core provides high strength and can withstand large rolling pressure and impact loads, ensuring the stability and safety of the rolling process. The steel core provides good thermal deformation resistance, maintains good shape stability even at high temperatures, and ensures the dimensional accuracy of rolled products. It is suitable for various rail rolling mills and can meet the rolling needs of metal blanks of different sizes and materials, including the rolling of various types of rails. Semi-steel rolls can improve the production efficiency of rolling mills. Semi-steel rolls have characteristics in terms of wear resistance, strength, thermal deformation resistance, production efficiency, and cost-effectiveness, and are suitable as roll materials for rail rolling mills.
