Lump grain granule Ca-Si-Ba inoculant silicon calcium barium

Si-Ba-Ca alloy is a kind of graphite can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic groups, refine the matrix structure, it has a good effect in a short time (about 5-8 minutes) after inoculation. Mainly suitable for various situations of general casting or late instantaneous inoculation.

The amount of inoculant used in the inoculation treatment of cast iron has little effect on the chemical composition of cast iron, but great effect on its microstructure, so it can improve the mechanical properties of gray cast iron, and also has obvious effect on its physical properties.

Good inoculation has the following effects:

Eliminate or reduce the tendency of white mouth;

To avoid the occurrence of supercooled tissue;

Reduce the sensitivity of the wall thickness of cast iron, so that the difference of the microstructure of the thin and thick section of the casting is small, and the hardness difference is small.

It is beneficial to nucleation of eutectic group and increase the number of eutectic group.
