Experimental and theoretical study of the efficiency of solid slag mixtures for desulfurization of 20GL steel under conditions of induction crucible melting

When producing steel, the enterprise faces difficulties in removing sulfur from the melt. In turn, an increased sulfur content in the finished product leads to a decrease in the values of some mechanical properties. This work analyzes the desulfurization process of 20GL grade steel in an induction crucible furnace. The influence of sulfur on the impact toughness of steel and the factors influencing sulfur removal are considered. Calculated data and industrial melting data were obtained, the difference between these data was explained, and recommendations were made based on this data. The parameters of steel smelting technology, which determine the chemical composition and structure, are the main factors contributing to high mechanical properties. The relevance of the work lies in the need to improve and develop the desulfurization process, which allows for the production of steel with low sulfur content and high mechanical properties.
