Silicon barium inoculant is mainly used in the inoculation of ductile iron and gray cast iron iron fluid. Silicon barium inoculant strongly increases the graphitization core, refines graphite, promotes the acquisition of A-type graphite in gray iron castings, and improves strength. For ductile iron castings, it can make the graphite in ductile iron fine and round, and improve the spheroidization level. Highly resistant to recession while preventing associated spheroidization recession. The wall thickness is less sensitive and the structure is uniform. Significantly reduces the tendency of white spots, reduces the relative hardness, and improves the cutting performance of castings. Used as inoculant and spheroidizing agent in the cast iron industry.
Compound inoculant ingredients:
Content: Si: 68%-72%, Ba: 2%-5%, Ca: about 1.5%
Supply particle size of inoculant:
0-0.25mm: used for in-mold inoculation (accurate inoculation and higher efficiency)
0.2-1mm: used for inoculation with flow (the control of inoculation amount is more accurate)
1-3mm and 3-8mm are used for incubation in the bag (the incubation time must be controlled at more than 70% of the tapping time)
8-15mm is used for incubation in the furnace;
