Integrated Ironworks & Steelworks is composed basically by a blast furnace plant and its auxiliary equipment, such as:
Stackers, reclaimers and cranes in yard, port, etc.
Material Handling units for additives (lime, dolomite, ferro-alloys, etc) and mineral –ore-, scrap yards, etc.
Coke Oven Batteries
Transportation systems: torpedo ladles to bear molten pig iron to BOS-BOF
Basic oxygen steelmaking: BOS, BOP, BOF (Basic Oxygen Furnace)
Secondary Metallurgy - refining: ladle furnace
Continuous Casting facilities: MCC
In a blast furnace is produced molten iron, operated in order to produce steel using the so called BOS process: Basic oxygen steelmaking (BOS, BOP, BOF), also noted as Linz–Donawitz-steelmaking.
This is a method of primary steelmaking in which carbon-rich molten pig iron is converted into steel.
Blowing by means of oxygen lances through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. This is a basic process mixing burnt lime or dolomite, both of them chemical bases, to remove impurities and protecting at the same time the lining of the converter.
After a subsequent refining process, in a ladle furnace, the molten steel is finally processed in continuous casting facilities as a step prior to its subsequent hot rolling
