How we make steel
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.
