Study of the influence of temperature and reducing agents on the chromium content in slag in the air atmosphere

Popis výsledku v původním jazyce

The paper presents the results of laboratory experiments of the reduction of chromium and its oxides from slag using carbon and silicon reducing agents. The study of chromium reduction from molten slag to molten steel was carried out for slag originating from the production of stainless steel with an average elemental content of 0.16 wt. % C, 16.25 wt. % Cr, 5.00 wt. % Ni and 1.05 wt. % Mo. Based on the literature studies experiments on chromium reduction from slag with high Cr2O3 content (16 wt. %) were designed, implemented, described and subsequently evaluated. The reduction was carried out using a reducing agent of carbon in the form of anthracite and silicon in the form of ferroalloy FeSi. The atmospheric conditions and pressure were used for experiments. The temperature of the slag was raised by an oxy-fuel burner and the carbon and silicon reducing agents were applied on the surface of the molten steel. The experiments confirmed the possibility of reducing up to 62 % of chromium from the molten slag back into the stainless steel melt.
