| Zusammenfassung: | The invention relates to a method for recovering iron-containing dust. The method comprises the following steps: S1, testing chemical components, phase composition, particle size distribution and other physical and chemical properties of the iron-containing dust generated in a steel smelting process; s2, different iron-containing dust is selected to test the influence of the iron-containing dust on the lowest assimilation temperature and the liquid phase fluidity of the mixed iron ore powder, and a model of the influence of the iron-containing dust adding amount on the high-temperature performance of the iron ore powder is constructed; s3, researching the influence of addition of different iron-containing dust on sintered ore performance indexes based on a sintering cup experiment, and constructing a quantitative influence relation model; and S4, in combination with iron-containing dust physical and chemical properties, high-temperature properties, sintering cup test results and industrial production data ana |
