Ductile Cast Iron: Process, Composition, Differences and .

Ductile Cast Iron: Process, Composition, Differences and .

Ductile iron casting refers to a process in which magnesium / cerium (as an alloy of magnesium / cerium) is added to cast iron. It reacts with the sulfur and oxygen in the molten iron and changes the way the graphite is formed. Ductile cast iron (also called as spheroidal graphite cast iron or nodular cast iron) has been widely used as a main industrial material in place of high-grade cast iron.

How Is Cast Iron Made? | Sciencing

How Is Cast Iron Made? | Sciencing

Cast iron that has not cooled evenly produces a low-quality cast. Other problems faced during the cast iron process include contamination of the iron, gas porosity (the forming of bubbles in the iron), and problems with the fluidity of the metal. The casting process is an art that must be examined and experienced to be fully understood.

Ductile iron is actually likely to expand during the casting process, as shown in the table found on the Casting Wikipeda page, which is in part cited from this casting text by Stefanescu. However, as the tables show, the range of volume change is fairly large and not one-sided, which is to say the ductile iron may either expand or contract depending on other conditions of the casting process.
