description: The object of the study is the technology of ladle-furnace processing of stainless steels in the production conditions of the electric furnace plant of LLC Â«NPO Laboratory of Special Steels and AlloysÂ». The aim of the work is to develop technological recommendations that allow increasing the recovery (recovery rate) of alloying elements from ferroalloys during ladle-furnace processing of stainless steels. Approaches used to solve the problem of the project: 1) study of the theoretical part (literary review); 2) data collection; 3) application of the theoretical part for calculations. In the course of the work, 138 heats of corrosion-resistant and heat-resistant stainless steel grades (08X18N10T, 10X17N13M2T, 15X11MF, 13X11N2V2MF) were considered. The data of open-hearth furnace charts, chemical composition according to the journal of bucket chemical analysis and technological features of ladle-furnace processing were studied. Based on the above, the recovery rate of alloying elements from ferroalloys given at the stage of ladle-furnace processing is calculated; the dependence of recovery on the specific consumption of finishing additions is determined. The results obtained during the qualification work can help to rationalize the consumption of ferroalloys at the stage of ladle-furnace processing during the smelting of stainless steel grades and obtain a positive economic effect.
