description: The topic of the graduate qualification work: "Influence of steelmaking on the quality of rolled steel". This work is devoted to the development of a model for calculating the desulfurization of steel with refining slag. The tasks that were solved during the study: - Analysis of the defects of the enterprises under consideration - Study of passports of melts, systematization and sorting them into good and defective - Improvement of the desulfurization calculation method by integrating new formulas of the desulfurization coefficient - Calculation of desulfurization coefficient - Calculation of final sulfur content - Calculation of refining slag The work was carried out on the basis of passports of melts of the considered Enterprises 1 and 2. Also the materials of research reports of the departmental laboratory of metallurgical expertise, compiled in the period 2018-2019, were analyzed in detail and used. The model was developed and the refining slag, desulfurization coefficients and the final value of sulfur of steels according to the data from the passports were calculated. The defects of these plants were also analyzed. As a result, we analyzed the steel production technology of the enterprises under consideration, calculated desulfurization for each heat from the passports, according to the developed model and analyzed the defects formed in the melts with defects. On this basis, effective technological recommendations for minimizing the resulting rejects in the production of
