This study focuses on the influence of the depth and proportion of solid fuel enrichment of surface-layer on the sintering process, physical indicators of the finished sinter, and solid fuel consumption. The results indicate that as the depth of solid fuel enrichment increases, the yield of sinter under varying burden thicknesses is consistently higher than the baseline values, showing a gradual upward trend. The average particle sizeParticle size of sintered ore increases, while solid fuel consumption decreases. With an increase in the proportion of surface-layer solid fuel enrichmentSurface-layer solid fuel enrichment, the sinter yield and tumbler strength initially rise and then decline. The highest sinter yield is achieved at a layered solid fuel proportion of 3%, while the maximum tumbler strength occurs at a proportion of 5%. Under different proportions of solid fuel enrichment, the percentage of 5–10 mm sinter particles is consistently lower than the baseline values, indicating that surface-layer fuel layering helps improve the sinter size distribution by reducing the proportion of 5–10 mm particles.
