Abstract

The analysis of the results of steel de-oxidation with manganese and silicon during tapping from an arc furnace in the Ural Steel is carried out. It is shown that the absorption of manganese and silicon during de-oxidation varies widely: from 33.0 to 88.4% (average 68.8%) for manganese and from 25.9 to 79.8% (average 63.8%) for silicon. The main causes of high varies and low absorption of deoxidizing agents were established: low carbon content and high metal overheating before de-oxidation. A statistical analysis of St 37-3 steel de-oxidation data was performed with the aim of improving the efficiency of steel de-oxidation technology in a ladle. The regression equations are obtained, allowing to calculate the assimilation of deoxidizers and the consumption of ferroalloys, depending on the temperature and carbon content in the metal during tapping from the arc furnace.
