Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat.Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to …

The peculiarity of pellets as agglomerated iron ore raw materials is their tendency to swell during reduction [16, 17]. Swelling occurs at the stage of reduction of wuestite to iron due to the slowing down of the formation of cores of a new phase and the growth of hairline iron crystals. The ISO 4698 standard (Iron ore pellets for blast furnace ...
