In the iron ore sintering process, a raw mix of fine particles of iron ore, limestone, and fuel coke fines form pseudoparticles after being mixed with water and these pseudo particles are then fed to the traveling grate to form a bed. After the feed material is introduced to the bed, combustion starts from the top of the bed by the ignition burner, and then the combustion front propagates ...

Phase Formation in Iron Ore Sintering

During the iron ore sintering process, iron ore fines (< 6 mm) are mixed with limestone flux and coke breeze and heated to ~1300ºC. This results in partial melting of the mixture, and converts the loose raw materials into a porous but physically strong composite material in which the iron bearing minerals are bonded together by a range of complex ferrite like phases known collectively by the ...
