Nov 04, 2020Sintering is one of the iron ore post-processing steps to prepare iron ore fines for a blast furnace (another common process of iron fines agglomeration is pelletizing, but this will be part of another blog). Feed for a sinter plant consists of iron fines, coke, and flux (eg limestone). The feed is placed on a sintering bed, where thermal

27.11.2019Both NiO–iron ore and CeO 2 –iron ore exhibited good cycle performance, while the sintering of the CuO–iron ore resulted in a decrease in the reactivity. Compared with the CuO–iron ore and CeO–iron ore, the NiO–iron ore was more appropriate for hydrogen production due to its high hydrogen yield and good cycle performance.

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. What is the sintering temperature?
