摘　　要：熔池熔炼技术由于熔炼效率高、原料适应性强等突出优点被广泛应用于铜、镍、铅、锡、锌等有色金属的冶炼.但在实际生产中,熔池熔炼仍存在熔池搅拌不充分、熔体飞溅严重、喷枪和耐火内衬寿命短等行业共性难题.从机理层面,熔池内呈现出高度非线性的混沌流动特征,涉及到气-液-固三相的传热、传质、相变和化学反应,导致现阶段对熔池内多相混合机理和过程强化机制的认识远不够深入,极大限制了该技术的发展.本文从混沌流非线性强化混合理论、顶-侧-底吹过程强化研究、多相混合效果定量评价方法三个方面,全面总结了有色金属熔池熔炼过程强化领域的最新研究进展,并展望了未来的发展趋势.Bath smelting technology is widely used in the smelting of nonferrous metals such as copper,nickel,lead,and tin due to its high efficiency,ease of operation,and strong applicability.However,in actual production,this method faces common industry problems,including insufficient stirring of the molten bath by the injected gas,severe melt splashing,and the short lifespan of the lance and refractory lining.From a mechanistic perspective,the fluid in the molten bath exhibits highly nonlinear chaotic flow characteristics,involving heat transfer,mass transfer,phase change,and chemical reactions among gas,liquid,and solid phases.This complexity has hindered a deep understanding of the enhanced mixing mechanisms in molten baths,thereby restricting the development of this technology.This paper comprehensively summarizes the latest research progress in the field of intensification of the nonferrous metal bath smelting process from three aspects:the theory of nonlinear intensification of chaotic flow mixing,the research on intensification of top-side-bottom blowing processes,and the quantitative evaluation methods of multiphase mixing effects.Finally,the development trends is prospected.
