Schematic Process flow of an integrated steel plant. Because every process step poses individual analytical requirements, there is no single analytical technique matching all requirements. In fact, multiple, complementary techniques are used and will become more imperative to optimize cost and quality.

The process of making steel starts at the Blast Furnace where the three ingredients, iron ore, limestone and coke are combined in precise ratios to form iron (not yet steel). The limestone helps separate impurities from the iron that is now a liquid. During the heat the iron, being heavier, settles to the bottom and slag floats to the top.
