Graphitic Cast Steel Rolling Mill Rolls

Graphitic Cast Steel Rolling Mill Rolls1. Description
The graphitic steel rolls have a metallographic structure consisting of carbides and a small amount of graphites in the pearlitic matrix. The rolls of this material has better tensile strength and better resistance to thermal cacking than adamite rolls of the same hardness, and the wear resistance of which is better than the cast steel rolls. Graphitic steel rolls are mainly used in the bill and roughing stand pf hot rolling mills; sections mills, tube mills, bar mills and wire mills.
