Injection characteristics of side-blown lance in a bath smelting furnace directly govern reaction intensity and smelting efficiency. In this study, stirring enhancement mechanism of a novel side-blown lance with an adjustable rotation angle was investigated by computational fluid dynamics (CFD), and structural parameters of the lance were optimized. A volume-of-fluid (VOF) multiphase flow model coupled with the realizable k-ε turbulence model was employed to conduct transient simulations of gas-liquid two-phase flow in an oxygen-enriched side-blown smelting furnace. Influence of lance rotation angle (0°, 15°, 30°, 45°, and 60°) on flow field and mixing performance of the molten bath was analyzed. Results indicated that lance rotation angle exerted a nonlinear control effect on bath hydrodynamics. A moderate rotation angle (around 30°) effectively enlarged gas-induced disturbance region, accelerated interfacial renewal, and improved the uniformity of bath stirring. In contrast, either a non-rotating angle (0°) or an excessively large rotation angle (60°) led to pronounced flow drift and deteriorated local mixing. Overall, the proposed side-blown rotatable lance, through appropriate optimization of rotation angle, can enhance bath stirring while simultaneously ensuring furnace lining integrity and prolonging lance service life. The findings provided a theoretical basis and engineering guidance for lance design and optimization in large-scale oxygen-enriched side-blown smelting furnaces.

侧吹熔池熔炼炉喷枪的喷吹特性直接决定炉内反应强度和冶炼效率。本研究基于计算流体力学（computational fluid dynamics，CFD）对一种可旋转调节角度的新型侧吹喷枪强化熔池搅拌的过程开展机理研究，并优化其结构参数。采用流体体积（volume of fluid，VOF）多相流模型耦合Realizable k-ε湍流模型，对富氧侧吹熔炼炉内的气-液两相流动进行瞬态模拟，考察喷枪旋转角度（0°、15°、30°、45°、60°）对熔池内流场和搅拌性能的影响。结果表明，喷枪旋转角度对熔池流动具有非线性调控作用。 适度旋转（30°左右）可扩大气体扰动范围、提升界面更新率并改善搅拌均匀性；而旋转角过小（0°）或过大（60°）均会导致流场偏斜和局部混合不良。综上所述，新型侧吹可旋转喷枪通过优化旋转角度，可在强化熔池搅拌的同时兼顾炉衬保护与喷枪寿命延长。本研究为大型富氧侧吹炉喷枪设计优化提供了理论依据和工程指导。
