Iron Rolls. 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.

Therefore, high chromium cast iron rolls were widely used in finish rolling front stands in the 1980s. At present, high-chromium cast iron composite rolls have been widely used as hot strip (steel) continuous rolling mills, rough rolling and finishing rolling front-end work rolls, and wide medium and heavy plates.
How to optimize the use of rolling mill rolls; Increase the production capacity of the rough rolling mill; High-chromium steel rolls were developed in Europe in the early 1980s, with the purpose of replacing roll materials with poor performance. Such as: semi-steel rolls, centrifugal cast infinite chilled cast iron (ICDP) or forged steel rolls.
