<p>With the introduction of low-carbon initiatives, China's metallurgical industry is undergoing a transition toward greener, low-carbon practices. Plasma technology, characterized by its high thermal performance, concentrated energy, significant chemical activity, rapid cooling rates, and controllable reaction atmospheres, has found extensive applications in this field. This paper reviews the advancements in plasma technology as applied to powder metallurgy, auxiliary combustion, and iron and steel production. In powder metallurgy, notable methods include discharge plasma sintering and plasma assisted combustion. In ironmaking, technologies such as plasma ironmaking and plasma direct reduction of iron oxide are employed. In steelmaking, plasma is utilized for melting, refining, and tundish heating processes. Currently, the application of plasma in sintering and auxiliary combustion remains limited, and there is a notable lack of in-depth research on direct reduced iron. Additionally, plasma metallurgy faces challenges, including short equipment lifespan, difficulties in controlling process parameters, and high costs. This paper proposes measures and methods to address these challenges, aiming to provide technical support for the large-scale application of plasma technology in metallurgy.</p>
