Inoculant is a special alloy added in the smelting of cast iron. Its main function is to improve the solidification structure and performance of cast iron, and to improve the quality and mechanical properties of castings. What are the advantages of inoculant in cast iron:
1. Improve the solidification structure: the addition of inoculant can promote the precipitation and grain refinement of carbides in cast iron, thus optimizing the solidification structure, reducing the internal defects of castings (such as pores, inclusions, etc.), and improving the mechanical properties and surface quality of castings;
2. Improve the strength of castings: the effect of inoculant helps to reduce the supercooling of molten iron, improve the phenomenon of white mouth, improve the toughness and strength of cast iron, so that the casting has good tensile, compressive and impact resistance;
3. Reduce the fracture rate: Appropriate addition of inoculant can improve the heat treatment performance of cast iron, reduce the fracture rate and shrinkage of castings, and increase the service life of castings;
4. Improve the surface quality of castings: the inoculant can reduce the oxidation and pollution of the cast iron surface, improve the surface finish and flatness, reduce surface defects, and help improve the appearance quality of castings.
