Molten iron is a key ingredient in the steelmaking process which takes place in the Slabmaking Plant. This Plant consists of an oxygen steelmaking furnace (KOBM) and a continuous slab casting machine. To produce steel, the KOBM uses a mixture of scrap steel and molten iron from the melters. Further refining occurs at the Ladle Treatment Station (LTS), where ferro-alloys are added to bring the steel composition up to its required specification. The molten steel from the LTS is then transferred to the continuous caster, where it is cast into slabs.
