Description
To minimise production costs for alloyed steel production in an electric arc furnace (EAF), optimal mixing of the molten metal is required during the melting and refining process. Improved heat transfer accelerates the melting of larger scrap pieces, resulting in time and energy savings. A homogeneous distribution of alloy elements and carbon in the melt reduces the unwanted oxidation of alloys, e.g. chromium, leading to better metal yield and improved slag properties.
Inert gas stirring is a proven method for improving process control, energy efficiency, metal yield, melting time, and metallurgical properties in such areas of EAF steelmaking as oxygen control and dephosphorisation. To support these benefits and meet the increasing demands of larger EAFs in integrated steel plants, the range of purging plugs has been expanded to accommodate the higher flow rates. The improvements in EAF process efficiency and metallurgy achieved with inert gas stirring are presented in industrial case studies.
