What is inoculation treatment?

What is inoculation treatment? In technical terms, a small amount of other substances are added to the liquid metal during solidification. Promote nucleation and inhibit growth. To achieve the purpose of refining the grains. But presumably such an explanation, many people do not understand. In plain language, the inoculation process is to add additives to the cast iron.

Silicon inoculant is an artificial composite ferro alloys product. The main application is with the production process of cast iron. 80% of Chinese foundry manufacturers are using barium-containing inoculants. In practice, Si-Ba inoculants can improve the performance of the product. So, it can be widely used in actual production.

In general, the amount of gray cast iron is 0.2~0.5%. For ductile iron, the amount is generally 0.5~1.1%. For cast iron horizontal continuous casting ductile iron, the general addition amount is 0.8~1.5%. The amount of use should be determined according to the actual situation. The relationship between iron and molten iron is very close. It should be adjusted according to the actual situation. Besides, after the inoculant is added, a local silicon-rich microdomain can be formed in the molten iron. This is good for graphite precipitation. The above is a brief introduction to two common inoculants. In fact, in actual life, there are many used as inoculants. CG Metal provides a variety of inoculant products.
