Alloy Chilled Cast Iron Rolls

Alloy chilled cast iron rolls are one kind of cast iron rolls, which contain almost no free graphite in the matrix of working layer of the barrel. They have hardness and excellent wear resistant, are suitable to finish stands of light bar and wire rolling mills and narrow strip mills. Its microstructure is fine pearlite and carbides.
