As one of the two main steelmaking methods, electric arc furnace (EAF) steelmaking has many advantages, such as low investment, low cost, and environmental safety. This study aims to improve the dynamic conditions of molten steel in EAF steelmaking by utilizing an efficient stirring method known as bottom-blowing technology. A numerical model was developed to simulate the 3D multiphase flows, incorporating gas, steel, and slag components. The research involved comparative analysis of various bottom-blowing gas flow rate distributions, namely uniform distribution versus non-uniform (linear and triangular) arrangements. The parameters obtained from the numerical simulations, alongside separated liquid steel analyses, provided insights into both metallurgical and dynamic outcomes in EAF steelmaking. Results indicate that the arrangement and intensity of bottom-blowing gas significantly affect the flow characteristics of molten steel, thereby improving the metallurgical reaction rates and the overall quality of the produced steel. This work contributes to a better understanding of the stirring mechanisms in EAF processes and supports the optimization of bottom-blowing technology for enhanced steel production efficiency.
