Siliciu aluminiu bariu calciu este un bun dezoxidant și desulfurizant în aliajele de bariu, care poate reduce oxigenul din oțel la un nivel mai scăzut. În același timp, oxizii complecși care conțin calciu, bariu, siliciu și aluminiu formați sunt ușor de plutit din oțelul topit. Oțelul topit este pur, iar rezistența la impact și performanța de prelucrare a oțelului sunt îmbunătățite.
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 la sută. Pentru parametrii echipamentului trebuie selectate un curent ridicat și o tensiune scăzută de lucru pentru a menține temperatura ridicată în zona de reacție a cuptorului.
