Abstract Scope To ensure a stable and efficient processing of scrap in an Electric Arc Furnaces (EAF) good slag foaming practice is essential. Foamy slag requires full control of the chemical composition of the slag in order to control the slag viscosity and gas generation rate. In the present work experiments have been performed with the aim to study the saturation of MgO in the Al2O3-MnO-CaO-SiO2-FeO slag used in the ConSteel EAF production at Celsa Armeringstål in Norway. Molten slag samples, with the FeO content ranging from 20-40% and the basicity (CaO%/SiO2) from 1.6-2.1, have been thermally treated at 1550-1750˚C at temperature steps of 100˚C. The chemical composition of each sample was later evaluated and used as input data for thermodynamically evaluating Isothermal Stability Diagrams (ISD) at constant basicity and temperature. The obtained results are compared and discussed in view of the data available in Factsage version 7.0 for the same system.
