Evraz Highveld Steel Process Overview

Iron making consists of 13 pre-reduction kilns and seven electric sub-merged arc smelting furnaces. Owing to the high titanium content of the magnetite ore Evraz Highveld receives from its Mapochs Mine, it cannot be smelted in the same way as more common iron ores in a conventional blast furnace, which relies on the presence of a large excess of carbon to reduce iron oxide to metallic iron.
