What is the difference between a silicon barium inoculant and a 75 silicon inoculant

Barium silicon inoculant is mainly used in the inoculation of nodular cast iron and gray cast iron. Si-barium inoculant strongly increases graphitization core, refines graphite, promotes the obtaining of A-type graphite in gray cast iron, improves the strength, for ductile iron can make the graphite in ductile iron fine, round, and improve the grade of spheroidization. Strong recession-resistant capability, while preventing the associated spherification recession. The sensitivity of wall thickness is small and the tissue is uniform. Significantly reduce the white tendency, reduce the relative hardness, improve the machining performance of casting. Used as inoculant and spheroidizer in the cast iron industry.

1, strongly increase the graphitization core, refine graphite, promote the gray cast iron to get A-type graphite, improve the strength, for ductile iron can make the graphite in the ductile iron fine, round, improve the grade of spheroidization.

2. It can effectively reduce the supercooling degree of molten iron, promote the precipitation of graphite, significantly reduce the tendency of white mouth, reduce the relative hardness, and improve the machining performance of casting.

3, strong anti-recession ability, anti-recession time is 2 times of 75 silicon, the amount of silicon barium inoculant is less than half of 75 ferrosilicon inoculant, while preventing the associated spheroidization recession.

4, the wall thickness sensitivity is small, improve the section uniformity, reduce the tendency of shrinkage and looseness.

5, the chemical composition is stable, the processing granularity is uniform, the composition and quality deviation is small.

6. Melting point is low (less than 1300°), it is easy to suck and melt when inoculating, and scum is very little;

75 silicon inoculant is the common 75 content of ferrosilicon, now many enterprises in order to improve the inoculation effect and prolong the inoculation effect will add some other alloy elements, such as barium, calcium, strontium and so on.
