Importance of slag quality control for flat steel products based on EAF process

The transition from an integrated to an electric steel process route, results in differences in the steel output for the electric arc furnace, as compared with basic oxygen steelmaking. A key parameter to control is steel cleanliness, alongside controlling the steel residence time in the ladle even where the tap level of sulphur and nitrogen are higher from the EAF. This article discusses the sulphur and nitrogen control needed to produce high quality grades based on proper slag quality control during secondary metallurgy processes.
