Iron Making | New Zealand Steel

Iron Making. Along with coal and limestone, the primary concentrate (ironsand) is heated and dried in one of four multi-hearth furnaces. It is then fed into the four reduction kilns, where it is converted to 80% metallic iron. Two melters then convert this into molten iron. The iron, at around 1480°C, is transferred to the Vanadium Recovery ...

Lime in the Steel Industry | Graymont

Among the many uses of lime in the steel industry, three stand out: Lime is used to convert iron into 'pig iron'. In the blast furnace, finely ground or granular limestone (with a low sulfur and alkali content) is used together with finely ground lime to convert ore into pig iron. The pig iron is later processed into steel.
