Foaming of EAF stainless steel slags with Cr2O3 using Steelcal has been examined in a 10 kg laboratory furnace at the AGH University of Science & Technology in Kraków, Poland. Steelcal (a modified grade of calcium nitrate) has been injected through a lance into the molten slag in a crucible electric arc furnace with one electrode. 22 tests have been performed changing such parameters as the slag composition, injection gas, pure Steelcal or mixed with C or FeSi. The slag height has been measured. Steel and slag analyses have been carried out. The results of the tests have been evaluated.
