The presented work presents the proposal, accomplishment and consequent evaluation of experiments based on the theoretical calculation and its comparison to the actually achieved level of chromium reduction from slag. The aim is reduction of chromium from slag with a high content of Cr2O3 with reducing agents of carbon in the form of anthracite and silicon in the form of ferroalloy FeSi. Experimental meltings in an atmospheric induction melting furnace were performed with an oxygen/fuel burner which was designed and produced for these experiments. Medium element contents in the melt during reduction were 16 % of Cr, 5 % of Ni and 1 % of Mo. The technology for chromium reduction from the slag was designed and experimentally performed with the aim of its transferability to the large metallurgical aggregate of intensified electric arc furnace.Keywords: Stainless steel, slag, chromium, carbon, silicon.
