Details
Ductile iron castings are an important type of cast metal material. They are made by adding alkaline earth metals or rare earth metals such as magnesium and calcium to the raw materials of ordinary cast iron. Ductile iron castings have advantages such as high strength, good toughness, thin walls, light weight, impact resistance, high bending performance, and easy installation. The casting processes for ductile iron include continuous casting, hot mold casting, and water-cooled centrifugal casting, with the water-cooled method being a state-of-the-art process worldwide.
Although the application of ductile iron casting technology is very widespread, improper operation during production can cause surface defects in the castings, such as shrinkage cavities and porosity. The causes and solutions for shrinkage cavities and porosity on the surface of ductile iron castings need to be analyzed and addressed according to the specific situation.
