| Abstract Scope |
Regulating the main oxygen flow rate of a coherent oxygen lance to influence the combustion jet core length is critical for improving electric furnace steelmaking efficiency. In this study, a three-dimensional numerical model of the combustion jet from an electric furnace coherent oxygen lance was established to analyze the variation in jet core length under different main oxygen flow rates. The results show that increasing the main oxygen flow rate can effectively extend the core length of the oxygen lance jet. When the main oxygen flow rate increased from 2000 Nm³/h to 2500 Nm³/h, the jet core length increased from 0.82 m to 0.88 m, representing an increase of 7.3%. With a further increase to 3000 Nm³/h, the velocity core length increased by only 4.5%, indicating a reduced growth rate. The results provide data support for controlling jet velocity attenuation and optimizing process parameters. |
