The Electric Arc Furnace (EAF) offers an alternative method of bulk steel manufacture. It makes steel from what would otherwise be unsightly and environmentally damaging scrap metals. It also consumes much less energy than the BOS furnace. Every tonne of EAF steel uses about 7.4 GJ of energy compared with about 16.2 GJ for every tonne of BOS steel.
Siting EAFs
Sites of EAF steelmaking in the UK are widespread. Since the Electric Arc Furnace does not depend on iron or the raw materials for making it, coastal sites have no particular advantage. In fact, these furnaces can be found anywhere in the UK where there is a good supply of scrap.
Furnace design
The EAF is a kettle-shaped structure with a removable lid. The three graphite electrodes that heat the furnace pass through this lid, which can be swung back when the furnace is being charged. The hearth of the EAF, where the metal is melted, is lined with a chemically basic and refractory material.
