Sažetak
Thermodynamic modeling of the process of deoxidation of steel with a different order of adding of deoxidizers has been carried out. For C82D steel grade, MnC17, FeV, SiC, FeCa were used as deoxidizers. It was found that the use of MnC17 for preliminary deoxidation, followed by the addition of FeV and SiC and the fi nal modifi cation of FeCa, makes it possible to provide a more favorable composition of non-metallic inclusions, which is represented by low-melting calcium aluminate CaO 6Al2O3 and a relatively low (~ 1 %) content of Al2O3, and also contributes to less silicon loss.
