Product Description
Indefinite chilled cast iron roll ring
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 martensite.
