At present, there are about 200 kinds of inoculants, and more than 30 kinds of common ones. Its classification methods are roughly as follows:

First, according to the composition of the composition, it is divided into: silicon inoculants, carbon inoculants, rare earth inoculants, etc.;

Second, according to the functional effect of inoculants, they are divided into: ink inoculants, stabilizing inoculants, and compound inoculants;

Third, according to the scope of use, it is divided into: gray cast iron for inoculants, ductile iron for inoculants, cast ductile iron for inoculants, creep ink cast iron for inoculants, etc.

The classification method we often use is to classify the components of the inoculant composition, so that the components of the components can be seen, and the characteristics of the inoculant can be known from the main components. Anyang Kangxin International Metallurgy ferroalloy supplies silicon barium inoculants, silicon calcium inoculants, barium silicon calcium inoculants, etc., with stable supply, a variety of particle sizes, and can be discussed when needed.
