Abstract

The importance of slag in metallurgy means that issues related to its physicochemical properties and the processes of its formation and movement on the surface of liquid metal are the subject of numerous studies. Two institutes of the Łukasiewicz Research Network have begun collaborating on observing the movement of slag on the metal surfaces using thermal imaging. The results obtained using this method will be used to improve numerical and physical models and optimize metallurgical processes. Initial tests of observing the movement of slag based on recording the change in the position of markers floating on the slag surface with a thermal imaging camera were performed in a laboratory electric arc furnace.
