Abstract

In the presented paper, the results of laboratory experiments aimed at the study of chromium and the behaviour of its oxides, together with its reduction mechanism with the aid of silicon and carbon, are given. Experimental heats were aimed at the proposal of a theoretical calculation of consumption of chosen reduction agents, a reduction study under laboratory conditions at the application of alloyed steel with a chromium content of ca. 9 wt. %, 13 wt. % and 18 wt. %, at temperatures of 1 600 °C and 1 650 °C, together with the change in the amount of reduction agents and the reduction period. The results will be used to verify the results obtained during half-operational and operational experiments that will imitate the operational conditions in the EAF.
