12.5 Iron And Steel Production

2015-9-10 · The sintering process converts fine-sized raw materials, including iron ore, coke breeze,limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charginginto the blast furnace. The raw materials are sometimes mixed with water to provide a cohesivematrix, and then placed on a continuous, travelling grate called the sinter strand. A burner hood, atthe beginning of the sinter strand ignites the coke in the mixture, after which the combustion is selfsupporting and it provides sufficient heat, 1300 to 1480°C (2400 to 2700°F), to cause surface meltingand agglomeration of the mix. On the underside of the sinter strand is a series of windboxes that drawcombusted air down through the material bed into a common duct, leading to a gas cleaning device.The fused sinter is discharged at the end of the sinter strand, where it is crushed and screened.Undersize sinter is recycled to the mixing mill and back to the strand. The remaining sinter

Iron and Steel Technology Roadmap – Analysis - IEA

While iron ore is the source of around 70% of the metallic raw material inputs to steelmaking globally, the rest is supplied in the form of recycled steel scrap. Steel production from scrap requires around one-eighth of the energy of that produced from iron ore – mainly in the form of electricity, rather than coal for production from iron ore.
