Adamite rolls consist of a cast iron outer layer and a steel core. The cast iron outer layer provides better wear resistance, while the steel core provides higher strength and hardness. The wear resistance of the cast iron outer layer enables the semi-steel roll to withstand the friction and wear of the metal blank, extending the service life of the roll. Compared with all-steel rolls and other materials, Adamite Rollers 200 (AD200) have lower manufacturing costs, but their performance can still meet the requirements of the rolling process and have good cost-effectiveness. It is suitable for various rolling mill equipment, including rough rolling mill, intermediate rolling mill finishing rolling mill, etc., and can meet the rolling needs of metal billets of different sizes and materials.
