Iron - Essential Chemical Industry

2021-8-17  Iron is produced by reduction of iron ore, which is often a mixture of oxides, using carbon, carbon monoxide, and hydrogen. While the blast furnace is the dominant reduction process other technologies are emerging which operate on a smaller scale. These are linked to locations where there is a plentiful supply of natural gas or low-grade coal.

12.5 Iron And Steel Production - US EPA

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
