Chilled Cast Iron Rolls for Rougher of bar wire and section mills
It is a kind of cast iron roll with free graphite in the matrix of its working layer.
It is shaped by Centrifugal Casting Machine, or by gravity casting.
Alloy chilled cast iron roll has high hardness and excellent wearability
Its microstructure is fine pearlite and carbide.
It is suitable for finish stands for small bar,
wire and section mills, as well as narrow strip mills.
