Abstract
The aim of the project `Better utilization of Cr-containing materials` was to save energy in ferrochromium and stainless steelmaking production by improving chromium yield and process efficiency. The main objective of the study was to measure activities of chromium oxides in process type slags. In this study, it could be determined first time, activities of chromium oxides at extended composition range. The results give a basis for construction of a more general model for chromium containing slags. By applying these results the chromium losses in the processes can be reduced and thus the energy and production costs can be lowered. Summarization of the slag studies, their results and eventual applications are shown as Appendix. Further, the project has included modelling and assessment of thermodynamic properties of iron-chromium based metal melts, survey of ferrochromium production technologies with energy consumptions and future trends as well as constructing of a calculation program for nitrogen pick up and removal in AOD-process
