Inoculant: Function and Application Analysis
Inoculants, as an important additive in the casting field, primarily function to improve the microstructure of cast iron, thereby enhancing the mechanical and processing properties of castings. By adding an appropriate amount of inoculant to the molten iron, it can promote the refinement and uniform distribution of graphite, effectively reducing the quantity of coarse graphite, enhancing the density of the matrix, and consequently increasing the strength, hardness, and wear resistance of cast iron. Additionally, inoculants can also reduce casting defects such as shrinkage cavities and porosity to some extent, optimizing the surface quality of castings. The application of inoculants is widespread in various types of cast iron production, such as gray cast iron, ductile iron, and vermicular cast iron, becoming a key technological means to improve product quality and reduce production costs. With the continuous advancement of materials science, the development of new types of inoculants is progressing towards more efficient and environmentally friendly directions to meet the growing industrial demands and promote the casting industry towards high quality and sustainable development.
