Product Description
We can provide the full ranges of rolls for the Bar & Wire mills, covering roughing rolls, intermediate rolls and finishing rolls.
Properties
The shell has a remarkable mechanical performance. With virtually no fall off in hardness due to the quantity of graphite remains
basically unchanged throughout the working layer. The hardness of roll depends mainly on the type of matrix, namely sorbite or marte
nsite.
