Process waste, collected from sinter plant, blast furnace and steel melting shop of an integrated steel plant contain high mineral values especially iron around 40%, 30%, and 55%, respectively, in form of hematite as major phase. The waste from blast furnace is carbonaceous in nature, along with iron it contains around 31% of carbon. ...

The ingredients – iron ore, coke and limestone fines – are carefully stacked and blended, then passed under an ignition hood at the sinter plant. This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnaces.

Sintering, which is also called 'frittage,' is the process of forming a solid mass of material through heat and pressure without melting to the point of liquefaction. This process involves the atoms in materials diffusing across the particle boundaries and fusing together into one piece. Sintering occurs naturally in mineral deposits, and ...

But that process has been proven to be a less effective way to control sinter quality because of the time delay. For example, typically it can take 6-8 hours to analyze the sample, calculate the adjustments, re-blend the raw materials, and make changes in the plant, so a lot of time and material have passed through the process.

The FINEX process is currently being operated at a scale of 1.5 Mt/yr hot metal [38]. The FINEX process is very similar to the COREX process; the major difference is that the FINEX process enables the direct use of sinter feed fine ore [37]. The scale of typical smelting reduction steelmaking plants is smaller than that of typical BF-based plants.
