Study of the Process of Processing Electric Steel Melting Dusts by the Method of Physicochemical Modeling

A physicochemical model of the recycling process of electric steelmaking dusts (ESM) with obtaining granulated pig iron and ZnO has been developed. The principal possibility of ESM dust processing by the proposed technology has been demonstrated. According to the model it is revealed that the main compounds in pig iron are Fe3C, Fe and FeS with the content, % by mass, respectively: 95,1 Fe; 4,89 C; 0,01 S, and in zinc-containing fumes, ZnO prevail with content 65,43 % by mass. The obtained modeling data are confirmed by the results of laboratory experiments on charge melting.
