Inoculants have significant advantages in steelmaking, which are mainly reflected in the following aspects:
1.Improving production quality and efficiency
Promoting graphitization: Inoculants can effectively promote the precipitation and spheroidization of graphite, especially in the production of ductile iron, it can significantly improve the strength and fineness of graphite, thereby improving the spheroidization grade.
Refining the matrix structure: By increasing the number of eutectic clusters, inoculants can refine the matrix structure, make the structure of the casting more uniform and dense, and improve the overall performance.
Improving graphite morphology and distribution: Inoculants can improve the morphology and distribution of graphite, reduce the tendency of white cast iron, and improve the mechanical properties and machinability of castings.
2.Reducing production costs
Reducing energy and manpower waste: Inoculants can reduce the time of steelmaking deoxidation, thereby saving energy and manpower costs.
Reducing smelting costs: The use of inoculants can also reduce smelting costs and improve the economic benefits of manufacturers. For example, ferrosilicon inoculants can replace part of the inoculants and spheroidizers to further reduce production costs.
3.Optimize product performance
Improve the machinability of castings: Inoculants can reduce the tendency of white spots and improve the cutting performance and mechanical properties of castings.
Reduce scum: Since the melting point of the inoculant is moderate and it is easy to absorb and melt, less scum is produced, which helps to improve production quality.
4.Environmental advantages
The use of inoculants can also reduce the impact on the environment to a certain extent, which is in line with the development trend of green and environmental protection in the modern metallurgical industry.
