| Abstract Scope |
Using stainless steel pickling sludge (SSPS) as a sintering ingredient allows for metal recovery, maximizes the utilization of its flux components (CaO). This study examines the impact of SSPS on the sintering performance and quality. It was noted that an increased proportion of SSPS (>1 wt%) in the sinter blend resulted in poor sintering performance. The presence of 5% sludge reduced the sinter utilization coefficient and yield by 0.32% and 4.67%, respectively, and also decreased the drum strength by 4.01% of sinter. The excessive formation of cuspidine reduced SFCA generation and weakened sinter bond phase strength. Adding 1% pickling sludge during the sintering process does not compromise sintering productivity and quality, offering guidance for the resource utilization of SSPS. |
