The silicon-barium inoculation line is a massive metallurgical material made by mixing silicon powder and barium powder according to the required proportion, and then making steel through a high-temperature furnace. It is an additive used in the casting process of the foundry. It has the characteristics of promoting graphitization, reducing the tendency of whitening, improving the shape and distribution of graphite, increasing the number of eutectic groups, and refining the matrix structure. It can be used in a short time after incubation treatment. It has good effect within 5-8 minutes.

Ingredients of barium silicon inoculation wire: Si: 60%-72%, Ba: 2%-6%, Ca: about 1.5%;

Silicon barium inoculation line is a necessary and very important smelting product for casting. It has good application in the production of gray cast iron and other cast irons. Gray cast iron has not yet been inoculated, the microstructure is unstable, the mechanical properties are low, and white walls of castings are easy to appear. The demand for white mouths in the casting industry is very large to ensure the quality of castings. Consistency and vaccination are crucial. However, due to the wide variety of inoculation lines, different inoculation lines have different characteristics, and users can choose different inoculants according to production needs. The entire production process of cast iron requires cooling, and attention should be paid to the cooling rate. Based on these data, the amount of inoculation line can be determined, which also plays a very important role in the quality of cast iron.
