The basic oxygen furnace (BOF) is responsible for over 60% of the steel production world-wide. Despite being an old and intensively studied process, the complex dynamics of the phenomena taking place in the BOF still challenge researchers and fuel debates. More-over, the severe operational conditions often prevent direct/continuous measurements of
