Silicon Barium Calcium

Silicon calcium barium is a good deoxidizer and desulfurizer. In the process of deoxidation, the three elements of silicon, calcium and barium promote each other, which effectively improves the utilization rate. Silicon-calcium-barium can reduce the oxygen content in steel, and the recovery rate of silicon, calcium and barium is higher than that of other alloys. At the same time, other complex oxides formed can easily float up from the molten steel, purify the molten steel, and improve the impact toughness and processing performance of the steel. Barium effectively reduces the vapor pressure of calcium in the steelmaking temperature range, and increases the solubility of calcium in molten steel. Compared with silicon-calcium alloys, when the alloy is used as a calcium source into steel slag, the recovery rate of calcium is significantly higher than that of silicon-calcium alloys. , And the stability of calcium in molten steel is also significantly improved. This shows that barium effectively protects calcium in steel slag and reduces the volatilization and oxidation of calcium, so as to achieve the purpose of treating molten steel.
