Silicon Barium Calcium (SiBaCa) inoculant is a high-performance composite alloy widely used in both steelmaking and iron casting. It is a new generation of inoculant that delivers superior deoxidation, desulfurization, and inoculation effects compared to conventional silicon-calcium alloys. The synergistic combination of silicon, barium, and calcium makes this alloy particularly effective for producing high-quality castings and special steels.
Silicon Barium Calcium alloy acts as an efficient deoxidizer, desulfurizer, and dephosphorization agent in steelmaking, significantly improving the purity of molten steel. Its strong affinity for oxygen allows it to form stable compounds that effectively remove impurities from the melt.
One of the most significant advantages of SiBaCa alloy is its ability to enhance calcium stability in molten steel. Barium effectively reduces the vapor pressure of calcium within the steelmaking temperature range, increasing its solubility in molten steel. Compared with silicon-calcium alloys, even when adding only half the amount of calcium, SiBaCa alloy can achieve approximately twice the calcium content in the molten steel.
The presence of barium and calcium ensures a long-lasting inoculation effect with slow decay, making it suitable for extended pouring times and large-section castings. This resistance to inoculation fading is particularly valuable for complex foundry operations.
Silicon Barium Calcium inoculant promotes graphitization, refines graphite structure, and increases the number of eutectic groups. It effectively reduces the tendency of white cast iron formation at edges and thin-walled areas, improving the machinability and mechanical properties of castings.
Silicon Barium Calcium alloys are available in various grades to meet different application requirements. Below are typical compositions:
Grade | Si (%) | Ba (%) | Ca (%) | Al (%) | Fe |
|---|---|---|---|---|---|
Si50Ba15Ca10 | ≥50 | 14-16 | 9-11 | ≤1.5 | Balance |
Si50Ba13Ca13 | ≥50 | 12-14 | 12-14 | ≤1.5 | Balance |
Si50Ba16Ca8 | ≥50 | 15-17 | 7-9 | ≤1.5 | Balance |
Si45Ba15Ca10 | ≥45 | 14-16 | 9-11 | ≤1.5 | Balance |
Si70Ba4Ca2 | 69-74 | 4-6 | 1-2.5 | 1-2 | Balance |
Si70Ba2Ca1.5 | 69-74 | 1-3 | 1-2.5 | 1-2 | Balance |
Note: Composition and particle size can be customized according to specific requirements.
Silicon Barium Calcium inoculant is available in multiple forms to suit different application methods:
Lump: 10- 50 mm, 10- 100 mm
Granule: 0.2- 1 mm, 1- 3 mm, 3- 8 mm, 3- 15 mm
Powder: 0- 0.2 mm
Particle size selection depends on the specific inoculation method—ladle inoculation, stream inoculation, or in-mold inoculation.
