1. It can greatly increase the graphitization core, purify graphite, promote the formation of type A graphite in gray iron castings, improve the strength and make the graphite in ductile iron fine and round, and improve the degree of spheroidization.
2. It can effectively reduce the subcooling of molten iron, promote graphite deposition, greatly reduce the tendency to form white iron, reduce the relative hardness, and improve the cutting performance of castings.
3. It has strong anti-degradation ability, and the anti-degradation time is twice that of silicon 75. The amount of silicon-barium modifier added is less than half the amount of silicon-iron modifier 75, and it can prevent the associated spheroidization recession.
4. It has low sensitivity to wall thickness, improves cross-sectional uniformity, and reduces shrinkage tendency.
5. It has a stable chemical composition, uniform processing particle size, and slight deviation in composition and quality.
6. It has a low melting point (below 1300°), easy to absorb and melt during inoculation, and has very little slag.
