steelTalks is a monthly series on topics of interest to the global steel community. The lectures are presented in a webinar format with a guest lecturer. In this steelTalk, Dr Ing. Ronald O’Brien, Instructional Designer at steeluniversity, will introduce the Electric Arc Furnace (EAF) and Secondary Steelmaking (SS) simulators. These tools enable participants to apply fundamental metallurgy concepts, run complete steelmaking simulations, and analyse data to optimise production decisions.
