摘要

This study analyzes the effect of adding a fourth coherent supersonic jet (CSJ) to an industrial electric arc furnace (EAF) that uses a three-CSJ configuration, seeking to improve steelmaking efficiency and quality. A computational fluid dynamics (CFD) model was employed to assess velocity distribution, turbulent kinetic energy (TKE), dead zones, penetration depth, and temperature uniformity in both three- and four-jet configurations; the existing three-CSJ configuration was compared with the proposed four-CSJ system. The results revealed that dead zones were reduced from 21.62 to 5.32%. Average velocity and TKE were improved from 0.050 to 0.152 m/s and 0.800 to 0.853 m2/s2, respectively. These changes resulted in improved mixing, deeper jet penetration, and more efficient decarburization. However, the additional jet created localized turbulence, diminishing temperature uniformity compared to the three-jet configuration.
