Barium silicate calcium inoculant

Strongly increase the graphitized core, refine graphite, promote A-type graphite in gray cast iron, improve strength, for nodular cast iron can make the graphite in nodular iron fine, round, improve the grade of spheroidization.

It can effectively reduce the undercooling degree of hot metal, promote the precipitation of graphite, significantly reduce the tendency of white opening, reduce the relative hardness, and improve the machining performance of castings.

It is easier to dissolve and absorb than the general inoculant, and can reduce the gas content in hot metal.

The anti-decay ability is strong, the anti-decay time is twice as long as that of 75 silicon, the amount of silicon-barium inoculant is less than half of that of 75 ferrosilicon inoculant, and the associated spheroidization recession is prevented.
