Si-Ba-Ca inoculants are ferrosilicon-based alloys containing a certain amount of calcium and barium, which can greatly reduce the occurrence of chilling and produce less slag. Therefore, Si-Ba-Ca inoculants are more effective than inoculants containing only calcium, and have the same inoculant effect as inoculants with higher calcium and barium contents. The combination of calcium and barium also controls chilling better than inoculants containing only calcium.
Si-Ba-Ca inoculants can effectively reduce the tendency of chilling in low-sulfur and high-sulfur gray cast iron and ductile iron. In low-sulfur cast iron, Si-Ba-Ca inoculants have superior performance over many other inoculants. Compared with other calcium-containing ferrosilicon inoculants, Si-Ba-Ca inoculants can also produce a large number of primary crystal nuclei at longer holding times. The appropriate amount of calcium, barium and other elements react to form less liquid slag. This makes the handling of molten iron easier and the quality more stable.
Si-Ba-Ca inoculants are suitable for gray cast iron and ductile iron. It can be flushed into the ladle when the iron is tapped or added during pouring. Regardless of the method used, attention must be paid to the selected particle size to ensure that it can be completely dissolved in the molten iron.
If the molten metal is kept warm for a long time before pouring, the inoculant will lose its ability to reduce the chill, so it is recommended to add the inoculant as late as possible. The Japanese silicon-barium-calcium inoculant can still maintain a large number of cores during the insulation period, and it is also suitable for large ladles and longer pouring times.
