Hello everyone, I am the youngest girl in the factory.
Today, let's talk about the treasure of the foundry industry-ductile iron castings.
Ductile iron castings are important casting metal materials developed in my country in the past 40 years. Due to the small stress concentration caused by spheroidal graphite, the fracture effect on the matrix is also small, so the tensile strength, plasticity and toughness of ductile iron are higher than other cast irons. Of course, ductile iron castings are not perfect.
In addition to general casting defects, they also produce shrinkage porosity, slag inclusion, subcutaneous pores, poor spheroidization, and recession.
