The transformation towards new technologies or the modification of existing processes for green steelmaking has to ensure, among other things, the implementation of circular economy concepts, e.g. slag recycling. Understanding how modifications affect slag characteristics is crucial for end applications. In the European project InSGeP, different models were developed to address this demand. This paper focuses on the use of an Electric Arc Furnace flowsheet model, simulating process behavior, steel and slag compositions for a feed containing Direct Reduced Iron or Hot Briquetted Iron. The model was tuned and validated with industrial and technology provider’s data and is being used for scenario analyses.
