Abstract
Under the conditions of converter production, a low carbon content (less than 0.002%) was achieved in electrotechnical isotropic steel (EIS) of the 4th alloying group (Si > 2.9% and Al > 1.0%). The results of the analysis of the influence of possible technological factors on the behavior of carbon in the metal during the decarburization stage (the state of the vacuum chamber before processing, the initial carbon content before vacuuming, oxidation, the lift gas flow rate, the treatment time at CVU KTs-1) using multivariate regression analysis mathematical model and theoretical calculations based on literary sources have been presented. The data obtained confirmed the possibility of achieving a carbon content in the metal of less than 0.002% after the decarburization stage at CVU KTs-1 of NLSM PJSC.
