Summary
Because of the increase of scrap usage aiming to increase circularity and to reduce CO2 emissions in steel production, the control of tramp and residual elements (TRE) is of high importance to low-carbon steel producers. Recycling steel, as a secondary raw material in low carbon steelmaking, represents a constraint to maintaining lower TRE levels in steel products, since end-of-life materials are mixed during the recycling process. The main concerning TREs include Cr, Cu, Mo, Ni, Mn and P.
This work aims to investigate how TREs distributed between steel, slag and fumes dust in an EAF. The main focus is on Cr, P and Mn. In this study, trials in a pilot EAF were performed. An overview of the pilot EAF and a description of the melting process are given in this paper. A comparison of thermodynamics with the operating regimes of the furnace in terms of carbon content in the metal bath and oxygen blow is made. Additionally, the level of iron oxidation during the process is taken into account.
Decarbonisation and digitisation will be major themes at this conference, both areas where the Institute is developing technologies and processes to support the optimisation of electric arc furnace production, while also reducing carbon emissions via this production route. This means that we are able to deliver significant value throughout the entire EAF plant project and operational life cycle.
