Secondary Metallurgy

Steel

Steelmakers use a secondary metallurgy vessel between the steelmaking and casting operations to allow molten steel to be brought to the required specification. Key operations can include deoxidation, desulphurisation and dephosphorisation. Not only does the use of secondary metallurgy enable a larger range of steel grades to be cast, but fine tuning steel composition in a separate furnace greatly improves the productivity of the main steelmaking unit. This is because with metallurgical adjustments taking place elsewhere, the time from steelmaking raw materials in, to tapped liquid steel out, is shortened.
