This paper describes interesting operational experiments have been performed in the scope of the project where the process of melting deoxidation was used under improvised conditions of cold blast cupola furnace. The goal was to find out metallurgical effects of added self-reducing briquettes prepared from steel sludge into cupola furnace charge and above all to verify the grade of deoxidation of oxides of iron at keeping output quality of cast metal. Present state of research and development of technologies of iron production in the area of commercial exploitation of these technologies is not in such a position that we could realistically assess their efficiency, investment costs and economic impacts. Moreover, an unequivocal requirement on minimization of CO2 emissions, mainly by its recycling, is here more and more promoted.
