Silicon Barium Calcium Alloy
Description
The silica-barium calcium alloy is a new type of composite alloy with high efficiency in barium series alloy. It is a deoxidizing agent, desulfurizing agent for steelmaking, and also has the function of dephosphorization. Barium can effectively reduce the vapor pressure of calcium and increase the solubility of calcium in molten steel. Compared with silicon-calcium alloy, silicon-barium-calcium alloy is used as the calcium source in the molten steel. Even if the amount of calcium added is half of the silicon-calcium alloy, the calcium content in the molten steel is about twice of silicon-calcium alloy. Calcium is also significantly increased in molten steel. It is clearly shown that barium effectively protects calcium and reduces the oxidation of calcium in the molten steel, thereby achieving the purpose of processing the molten steel with calcium.
