Silicon barium calcium is a good new deoxidizer in steelmaking, and it has good desulfurization and phosphorus ability. It plays a very important role in the smelting of steel with low sulfur and phosphorus. It has a wide range of applications in special steel systems.
Silicon Barium Calcium Character and use:
(1) Silicon barium calcium alloy is a new type of high efficiency composite alloy in barium alloys. It is a deoxidizer, desulfurizer, and dephosphorization agent for steelmaking; it is an inoculant and modifier in casting.
(2) 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 alloy, silicon barium calcium alloy is used as a calcium source to add to molten steel. Even if the amount of calcium added is half the amount of silicon-calcium alloy, the calcium content in molten steel is about twice that of silicon-calcium alloy. Calcium is also significantly improved in molten steel. It fully shows that barium effectively protects calcium in molten steel and reduces the oxidation of calcium, thereby achieving the purpose of calcium treatment of molten steel.
