The heat consumed in the sintering process is about 33% of the total heat input to the plant, with about 49% released to the atmosphere. Heat recovery at the sinter plant is a means for improving the efficiency of sinter making (Tian et al. 2019). There is opportunity to tap this sensible heat and utilize to preheat the combustion air for the ...

In addition to solid state and liquid phase sintering, other types of sintering, for example, transient liquid phase sintering and viscous flow sintering, can be utilized. Viscous flow sintering occurs when the volume fraction of liquid is sufficiently high, so that the full densification of the compact can be achieved by a viscous flow of grain–liquid mixture …

The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an open-grained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.
