Scrap Melting in DC-EAF Operations Using CFD Simulations

Direct current electric arc furnace (DC-EAF) leverages direct current to produce an electric arc for heating and melting of scrap steel. Its importance lies in its ability to increase production efficiency and optimize energy consumption. This project developed an integrated, comprehensive, 3D CFD model to investigate scrap melting processes in industry-scale DC-EAFs. The electric arc model is established to determine arc energy distributions. The coherent jet model simulates burner performance. The scrap melting model captures scrap collapse and melt. The integration of the three models is able to simulate the scrap melting stage in an industry-scale DC EAF.
