The ductile iron rolls contains alloying elements such as nickel, manganese, chromium, and molybdenum, which enhance its overall properties.
SG Iron matrix features an acicular structure (bainite + small martensite), which, as a result,ductile iron rolls offers higher strength and improved durability when compared to pearlite spheroidal graphite. Consequently, this structure enhances the overall performance of the ductile iron rolls.
Ductile Cast Iron is produced by two methods: static casting and centrifugal casting.
SG Iron the high alloy content and high casting fatigue.
Using the centrifugal composite casting process, we can achieve the ideal comprehensive performance.Using the centrifugal composite casting process, we can achieve the ideal comprehensive performance.
Compared to pearlitic cast iron, ductile iron rolls exhibits higher strength, toughness, and wear resistance.
We can produce the Ductile Cast Iron using static or centrifugal casting, which extends service life and reduces production costs, bainite, and martensite matrix structures, while graphite is spherical in shape, Ductile Cast Iron have good thermal conductivity, and has high tensile strength.
