What is the role of inoculants

The inoculant is a kind of inoculating agent that can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic clusters, and refine the matrix tissue, which has a good effect in a short time (about 5-8 minutes) after the incubation treatment. It is mainly suitable for general or post-instantaneous pregnancy in various situations. What is the role of inoculants?

1. Eliminate or reduce the tendency of white mouth;

2. Avoid supercooling tissue;

3. Reduce the wall thickness sensitivity of iron castings, so that the difference in microstructure at the thin and thick sections of castings is small, and the difference in hardness is also small;

4. It is conducive to eutectic nucleation and increases the number of eutectic clusters;

5. The morphology of graphite in cast iron is mainly fine and evenly distributed A-type graphite, so as to improve the mechanical properties of cast iron.
