Physicochemical regularities of complex reduction of iron chromite

Physicochemical patterns of complex reduction multicomponent charge have been studied in the absence liquid phases order to obtain spongy ligatures. The contained both simple oxides and oxide compounds. was conducted being realized at expense carbon gases (CO H2) as well with participation carbide phase, which formed during process. dependence phase composition products on initial ratios O/(C+H) C/H determined. possibility presence Femet shown increasing ratio formation based (1/60 Fe3C+1/3 Cr3C2). temperature limits appearance metallic theoretically determined thermodynamic modeling system Cr–Fe–C–O–H using software HSC Chemistry 5.1 results X-ray analysis products. equilibrium gas for iron chromite under different conditions calculated. To evaluate kinetic features chromite, rate Fe(CrO2)2 chemical-catalytic action. Salts alkali metals (potassium sodium) were used catalytic additives. influence temperature, reducing agent nature amount additive process investigated. Conclusions type optimal proportion additives made. mechanism characteristics analyzed.
