Spheroidal Graphite Cast Iron Rolls

The feature of ductile iron material is that the graphite is spherical in the as-cast state, its properties are similar to the alloy's infinite cold hardening roll, and its strength is higher than the infinite cold hardening roll.

Ductile iron rolls are rolls made of ductile iron material, which has some unique properties and application areas. Ductile iron is an iron alloy obtained by adding magnesium or earth elements to cast iron to obtain spherical graphite. Ductile iron has better wear resistance than ordinary cast iron and is suitable for rolls that are subject to wear. Ductile iron has good fluidity and filling properties and can be cast into complex roll shapes. Ductile iron rolls are widely used in various industrial fields, especially in those occasions that require high toughness, wear resistance, and cost-effectiveness. However, they may not be suitable for working environments with extremely high temperatures or high pressures, or those applications that require extremely high hardness and strength.
