In order to improve the recycling rate of iron-containing solid waste and reduce CO₂ emissions in steel mills,the technology of preparing blast furnace pellets from such materials as iron-containing dust sludge, BF return fines and steel slag powder by cold consolidation manner is studied. The results show that, when 30% BF return fines + 10% iron-bearing dust sludge +60% steel slag powder and 5% adhesive A are added,the compressive strength of dry and cold-consolidated pellets(forming pressure of 5 MP) can reach more than 2 500 N/P after drying at room temperature for 4 days; the compressive strength of cold-solidified pellets can reach 2 300 N/P after drying at 80 ℃ for 180 min, and the low-temperature reduction pulverization index,drum index,reduction expansion rate and compression set indexes of the two dried pellets can also meet the physical properties and metallurgical performance technical indexes of iron ore pellets.
