Slag plays an important role in steelmaking process by providing an insulation of liquid metal surface, preventing heat losses and removing impurities and inclusions in liquid steel, etc. For these reasons, in order to produce “a cleaner steel” attention should be paid on controlling of chemical and also physical properties of slag in steelmaking process. Initial formation of ladle furnace slag consists of carry-over slag of converter tapping and tapping additions. In this study, effects of different tapping additions to ladle slag conditions and steel cleanliness were investigated. Additionally, Sulphur removal capacities of slags were compared by means of chemical and physical properties with using FactSage Computational Thermochemistry Software and ARL Spark-DAT inclusion analyzer.
