To increase abrasion resistance, a cast-iron roll is given a carbidic running-surface layer which has a defined depth of at least 1 mm and a fine-grained structure whose cementite dendrites have a length of at most 100 m and a thickness of at most 20 m. The fine-grained structure is produced by remelt hardening of the outer surface of the roll.
Bainitic and bainitic martensitic nodular iron are nodular grades alloyed with Cr, Ni, and Mo with higher Cr and Ni contents. Compared to pearlitic irons, acicular irons show higher strength, toughness and wear resistance. The rolls can be cast static or spun cast depending of the size of the working layer and the mill conditions. Application.
