Abstract

Microwave heating, as an innovative green metallurgical technology, demonstrates extensive application prospects in the metallurgical field with unique advantages such as selective heating, volumetric heating, and rapid heating. Compared to traditional heating methods, microwave fields can significantly alter the kinetic behavior of metallurgical reactions and influence the evolution of material microstructures, thereby providing novel technical pathways for enhancing reaction efficiency, reducing energy consumption, and improving resource utilization. This paper systematically elucidates the fundamental principles of microwave heating and its application characteristics in metallurgy, conducts in-depth analysis of the impact mechanisms of microwave fields on reaction kinetics, explores the evolution patterns of material microstructures, phase compositions, and microstructures under microwave irradiation, and reveals the physicochemical mechanisms underlying microwave-induced reaction enhancement.
