What is the main action of silicate barium inoculant？
1.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.
2.The decay resistance is twice that of 75 silicon, and the amount of barium silicate inoculant added is less than half that of 75 ferrosilicon inoculant, while preventing the associated spheroidification decay.
3, Strongly increase 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.
4,The chemical composition is stable, the processing granularity is uniform, the composition and the quality deviation is small.
5, The sensitivity of wall thickness is small, the uniformity of section is improved, and the tendency of shrinkage and looseness is reduced.
6. Melting point is low (less than 1300°), it is easy to absorb and melt when inoculating, and scum is very little.
