The use of silicon barium calcium

As a composite deoxidizer, silicon barium calcium is widely used in the steelmaking industry. It is a very good composite deoxidizer. Due to its special element cost content, it has a strong desulfurization and dephosphorization ability, and it also has the function of an inoculant. Silicon-barium-calcium is a very good new deoxidizer in steelmaking, and has good desulfurization and phosphorus capabilities. It plays a very important role in smelting steel types with low sulfur and phosphorus content, and has a wide range of applications in special steel systems. prospect. Silicon-barium-calcium alloy is a new type of composite alloy among barium alloys. It is a deoxidizer, desulfurizer, and dephosphorization agent for steelmaking; it is an inoculant and modifier in casting. Barium 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, if silicon-barium-calcium alloy is used as the calcium source to add to molten steel, even if the amount of calcium added is half of that of silicon-calcium alloy, the calcium content in molten steel is about twice that of silicon-calcium alloy. , Calcium is also significantly increased in molten steel. It fully shows that barium protects calcium in molten steel and reduces the oxidation of calcium, thereby achieving the purpose of calcium treatment in molten steel. Silicon-aluminum-calcium and silicon-barium-calcium are both calcium-based new composite alloys that have been purchased by many steel manufacturers, but silicon-aluminum-calcium and silicon-barium-calcium are very different, and there are many differences in element content. Silicon The content of aluminum element in aluminum-calcium is relatively high, so silicon-aluminum-calcium is more suitable for deoxidation and desulfurization, while silicon-barium-calcium is relatively higher than barium element. Barium element can play a good role as an inoculant in steelmaking. Therefore, manufacturers You can choose according to your own needs for the product.
