Le calcium de baryum d'aluminium de silicium est un bon désoxydant et désulfurant dans les alliages de baryum, ce qui peut réduire l'oxygène dans l'acier à un niveau inférieur. Dans le même temps, les oxydes complexes contenant du calcium, du baryum, du silicium et de l'aluminium formés flottent facilement à partir de l'acier fondu. L'acier fondu est pur et la résistance aux chocs et les performances de traitement de l'acier sont améliorées.
Silicon aluminum barium calcium has a wide range of applications, but the main field is the application in steelmaking. What role does it play? Let's give you a brief introduction. The deoxidizing ability of composite deoxidizer is strong, which can obviously improve the advantage of molten steel purity. Many research institutions and iron and steel enterprises pay general attention to it, which has become a hot research and development situation, especially British Airways, which contains alkaline earth element in silicon. Ca aluminum barium composite deoxidizer is a more active research, and the technology is an essential part in the steelmaking process, which is called liquid steel deoxidization. However, it is a particularly important reducing agent. Now let's not talk about silicon aluminum barium deoxidizer. From the perspective of the development of steel in the past, pure aluminum was originally used, and aluminum was not easy to penetrate silicon steel aluminum barium. The production of silicon aluminum barium limited the use of aluminum. Silica, bauxite and coke are mixed evenly and added into the submerged arc furnace for smelting to produce silicon aluminum barium calcium alloy. Then CaO and coke are added in batches to promote the formation of silicon, calcium and aluminum. Then barium ore and coke are added in batches to promote the formation of silicon calcium barium aluminum alloy. Generally, the composition of silicon calcium barium aluminum alloy is: Si>30%, Ca>6%, Ba>9%, Al>8 pour cent. Un courant élevé et une basse tension de fonctionnement doivent être sélectionnés pour les paramètres de l'équipement afin de maintenir une température élevée dans la zone de réaction du four.
