[0002] Ductile iron is a high-strength cast iron material with comprehensive properties close to those of steel. Based on its excellent performance, it has been successfully used to cast some parts with complex forces and high requirements for strength, toughness and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material second only to gray cast iron. The so-called "iron instead of steel" mainly refers to ductile iron. Ductile iron is obtained by spheroidizing and inoculating spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thereby obtaining a higher strength than carbon steel. However, in the production and manufacturing of ductile iron parts, a variety of powdered raw materials need to be added, and the amount of addition needs to be precisely controlled.
