1. Silicon calcium barium alloy is a new type of deoxidizer used in steel production. It can improve the inclusion content and the gas element content in steel, reduce costs, and save aluminum. An effective new technology that can replace ordinary alloys and pure aluminum for smelting The final deoxidation of the steel process is especially suitable for the deoxidation requirements of continuous casting molten steel. Practice has proved that it not only meets the deoxidation requirements but also has desulfurization performance. 2. As a deoxidizer for steelmaking, this product can save 15-25% in the final deoxidation of molten steel in converter steelmaking or electric furnace steelmaking, and the total amount of oxide inclusions is reduced by an average of 29%. Improve the morphology of non-metallic inclusions in steel, finer than grain, and increase the strength value of steel by 6.14%. The content and recovery rate of acid-soluble aluminum in the steel are increased, which can effectively improve the quality of the steel and the mechanical properties of the steel. Silicon calcium barium alloy is a new high-efficiency composite alloy among barium alloys. It is a deoxidizer, desulfurizer, and dephosphorization (BaP2, BaP3) for steelmaking, and it is an inoculation modifier in casting. 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, when silicon-calcium-barium alloy is used as calcium source to add calcium into 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. , the stability of calcium in molten steel is also significantly improved, which shows that barium effectively protects calcium in molten steel and reduces the oxidation of calcium, thus achieving the purpose of calcium treatment in molten steel. Silicon, calcium and barium is a good deoxidizer. In the process of deoxidation, the three elements of silicon, calcium and barium promote each other, which effectively improves the utilization rate. Features: 1. Strong deoxidation ability and good molten steel fluidity completely solve the problem of nodules in the continuous casting nozzle. 2. Significantly improve the recovery rate of silicon manganese, etc. and reduce the amount of carbon powder added 3. The desulfurization effect is remarkable and the steelmaking cycle is shortened 4. It has a wide range of applications, and can replace all or part of the deoxidation materials in steelmaking such as aluminum wire, silicon aluminum barium, silicon calcium wire, etc. according to the process requirements, reducing the cost of deoxidation. 5. Easy to use, simple to operate, no need to add any auxiliary equipment.
