The role of alloy inoculant in cast iron

2025-05-08

Inoculant is a special alloy added during cast iron smelting. Its main function is to improve the solidification structure and properties of cast iron and improve the quality and mechanical properties of castings.

 

What are the advantages of inoculants in cast iron:

  1. Inoculants can improve the solidification structure: the addition of inoculants can promote the precipitation of carbides and grain refinement in cast iron, thereby optimizing the solidification structure, reducing internal defects of castings (such as pores, inclusions, etc.), and improving the mechanical properties and surface quality of castings;

 

  1. Inoculants can improve the strength of castings: the role of inoculants helps to reduce the supercooling of molten iron, improve the white cast phenomenon, improve the toughness and strength of cast iron, and make the castings have good tensile, compressive and impact resistance;

  1. Inoculants can reduce the fracture rate: the appropriate addition of inoculants can improve the heat treatment performance of cast iron, reduce the fracture rate and shrinkage of castings, and increase the service life of castings;

 

  1. Inoculants can also improve the surface quality of castings: inoculants can reduce the oxidation and contamination of the surface of cast iron, improve the surface finish and flatness, reduce surface defects, and help improve the appearance quality of castings.
