discount Deoxidizer Si-al-fe alloy is a kind of deoxidizer used in steelmaking, which can improve the form of inclusions and reduce the content of gaseous elements in liquid steel. It is an effective new technology to improve steel quality, reduce cost and save aluminum. The use of silicon aluminum ferroalloy It is especially suitable for deoxidation of molten steel in continuous casting. Practice has proved that it not only meets the deoxidation requirements of steel making, but also has desulfurization performance and has the advantages of heavy ratio and strong penetration. Advantages of silicon aluminum ferroalloy: The deoxidation of si - al - fe alloy is proved to be effective in practice. Compared with aluminum deoxidation, not only the yield of aluminum is higher, the amount of residual aluminum is easy to control, but also the morphology of inclusion is improved. After adopting si-al alloy, the element recovery rate is high, mainly because the proportion of the alloy increases, the proportion of aluminum is 2.7g/cm3, the proportion of si-Al-Fe (FeAl30Si20) is 3.5-4.2g/cm3, the proportion of final slag is generally 2.8-3.2g/cm3, so the alloy will sink below the slag surface after joining. The reaction of aluminum with air and oxygen in slag is controlled effectively. Deoxidation effect is good, it is generally believed that the generation of complex deoxidation products, oxide activity is reduced, conducive to deoxidation reaction. In addition, it is easy to form a low melting point phase, so that the inclusion is easy to polymerize and promote the removal of upward float. The total aluminum content in the steel is higher in the former than in the latter, while the acid soluble aluminum in the latter is higher than in the former, indicating that the aluminum oxide inclusions are greatly reduced when the ferrosilicon is used. discount Deoxidizer website:http://www.shenglongtrading.com/industried-silicon/deoxidizer/
