Abstract

1. Способ переработки железоцинксодержащих материалов, включающий стадии смешения и скатывания железоцинксодержащих материалов и оборотных пылей с твердым углеродистым восстановителем и стадию вельцевания окатышей, отличающийся тем, что на стадию скатывания 90-95% твердого углеродистого восстановителя подают в виде фракции -0,2 мм, а процесс вельцевания проводят при содержании железа в загружаемых в печь окатышах 30-60% и при соотношении железа к углероду по мольному весу равном 0,7-1,0 к 1,0.2. Способ по п.1, отличающийся тем, что размер окатышей составляет 15-40 мм.1. A method for processing iron-zinc-containing materials, including the stages of mixing and rolling of iron-zinc-containing materials and circulating dusts with a solid carbonaceous reductant and the stage of Waelz pellets, characterized in that 90-95% of the solid carbonaceous reductant is fed to the rolling stage in the form of a fraction of -0.2 mm, and the Waelz process is carried out with an iron content in the pellets loaded into the furnace of 30-60% and with a ratio of iron to carbon by molar weight equal to 0.7-1.0 to 1.0. The method according to claim 1, characterized in that the size of the pellets is 15-40 mm.
