Alloy Nodular Cast Iron Rolls
Goods&specification（mm）:∮490—∮850
Goods net weight:2000kg—9000kg
Product introduction:
This roll is characterized by the sphericity of graphite, its properties are similar to those of alloy infinite chill rolls, and its strength is higher than that of infinite chill rolls. Static casting is generally used.
Product feature:
It has high wear resistance, strong toughness and good thermal crack resistance, at the same time the hardness difference is small.As a result of spheroidal treatment, graphite carbon in cast iron changed from flake to ball, which eliminated the stress concentration of graphite tip caused by flake graphite, and greatly improved the strength of cast iron, which was similar to that of cast steel roll, but much higher than that of cast steel roll in wear resistance.
Product Application：
Small section steel, rod and wire and narrow strip mill stand; Hot - rolled flat sheet mill.
