Cluster Mills | Metal Processing Machinery | American Steel
Tags Rolling Mills; Cluster Mills. In all cases, one of the main advantages of a cluster mill is the large back up rolls. The back up rolls act as a heat sink because there is a considerable amount of heat energy going into the strip and the work roll. Much of the heat in the work roll is transferred to the back up roll.
