WEBOct 29, 2023 · Iron ore sintering was a semimelting process. Firstly, iron ore particles reacted with fluxes and generated liquid phase at high temperatures. Then, the liquid phase combined the dispersive unreacted iron ore (usually the core of coarse particles), and the liquid phase recrystallized and formed the bonding phase during cooling [12, 13]. In the ...
WEBJan 20, 2023 · The contents of the stack emissions are a combination of process fumes and dedusting dust. The reddish appearance is due to the dust particles containing micro fines of iron ore that either leak through the sinter bed or are captured by the dedusting system. An efficient ESP should be able to filter these particles (100 to 150micron size).
