Sulfur Migration Behavior in Sintering and Pelletizing Processes: A Review

As essential materials, iron and steel, which form the core of many national economies, guarantee the survival and development of the country. However, the iron and steel industry is also a typical example of an industry with high energy consumption and high pollution levels. Against the backdrop of a double carbon and green environment, the steel industry still needs to achieve high‐quality development. The sintering and pelletizing processes are one of the limiting links that need to be broken through. This article focuses on the source, change process, and emission modes of sulfur in the sintering and pelletizing processes, and also systematically introduces the migration behavior and law of sulfur, along with several typical desulfurization processes. Finally, the future green development of the iron and steel industry is considered.
