Abstract：The iron and steel industry produces large quantities of solid waste. In general, producing 1 t of steel generates about 600 kg of solid waste, and the proportion of dust and mud accounts for about 5%- 8% of the steel output. For a long time, the treatment and comprehensive utilization of solid waste have been paid great attention in Masteel, and the reduction, harmless and resource utilization of solid waste is taken as the important goal of internal production management. The research work and comprehensive utilization practice of Fe- containing dust in Masteel in recent years are introduced. On the basis of the classification of Fe- containing dust, the resource utilization system for the transfer and return sintering of the converter BOF OG sludge pipe, the comprehensive utilization system for the low zinc Fe- containing dust strong mixing pile building, and the system for the treatment of zinc- bearing dust by the rotary hearth furnace and the rotary kiln are built in Masteel. The produced all kinds of Fe- containing dust are synthetically utilized. Each year, about 178 thousand tons of CO2 emissions and 300 thousand tons of new water consumption can be reduced. At the same time, a large number of valuable elements such as iron, zinc, calcium and magnesium have been recovered. While significant social benefits have been achieved, rich economic returns have been obtained.
