Description

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
