By adding an appropriate amount of alloying elements and a special heat treatment process,the work layer of roll can be bainite matrix-based organizations with relatively high strength,toughness and wear resistance,while acicular nodular iron has a small hardness drop.At the same time the core has a higher intensity by separate nodulizing.
