ABSTRACT

As the steel industry's demand for efficient and environmentally friendly production processes continues to increase, the precise control of the temperature field of the hydrogen-rich vertical furnace as an important reduction equipment has become the key to ensuring smelting quality and energy utilization efficiency. However, the existing oxygen injection technology still has problems in temperature distribution control, such as difficulty in optimizing injection parameters, non-uniform temperature field, and insufficient heat and mass transfer efficiency. To this end, this paper systematically studies the influence mechanism of oxygen injection parameters (such as injection rate, injection angle, and oxygen concentration) on the internal temperature field of the hydrogen-rich vertical furnace based on numerical simulation methods. By establishing a multi-physics field coupling model, the refined simulation of the temperature, flow field, and reduction reaction in the furnace is realized, and the regulation effect of the injection strategy on temperature uniformity and local hot spot formation is deeply analyzed. The research results show that the optimized oxygen injection parameters significantly improve the uniformity of the temperature field in the furnace and improve the heat transfer efficiency. The temperature control indicators such as the maximum temperature difference are reduced by 15%, and the area of the local high temperature zone is reduced by 20%, which effectively promotes the stable and efficient operation of the reduction process. The numerical simulation framework and injection optimization method of this paper provide a theoretical basis and technical support for the intelligent control of the temperature field of the hydrogen-rich vertical furnace, and have strong engineering application value.
