In order to address the shortage of high-quality scrap for steel production, this study investigates a novel substitute in the form of decarbonized granular pig iron (DGPI). The objective was to analyze the decarbonization mechanism and evaluate the technical process of DGPI compared to traditional direct reduction iron (DRI) processes. The methodology entailed examining the carbon oxidation and removal processes of granular pig iron under specific oxidizing atmospheres, alongside comprehensive assessments of product quality and operational efficiency. Results indicate that DGPI not only meets the quality standards required for conventional scrap but also offers enhanced performance characteristics, such as lower construction investments, increased operational flexibility, and improved production efficiency relative to direct reduction methods. Furthermore, due to the abundant low-cost nature of granular pig iron and its production viability within existing steelworks, DGPI emerges as a promising solution to the dual challenges of scrap quantity and quality in the steel industry. This innovative approach is proposed as an effective alternative in the evolving landscape of steel production, particularly in resource-constrained environments like China.
