PURPOSE:To improve the strength and yield of sintered ore by enriching only a surface layer with fuel and pressing the surface layer. CONSTITUTION:A surface layer stirring unit 6, a fuel adding unit 7 and a press roller 8 are placed between an ore feeding vessel 2 and a firing furnace 4 in a Dwight-Lloyd type sintering apparatus. The surface layer of blended starting materials 1 is stirred before the materials 1 enter the firing furnace 4, and fuel is supplied only to the surface layer from the fuel adding unit 7 to form a fuel enriched layer of 2-100mm thickness. This surface layer is pressed with a press roller 8 to increase the density of the surface layer corresponding to eta30% of the thickness of the whole layer of the blended starting materials 1. The surface of the surface layer is then fired in the firing furnace 4, and the starting materials 1 are sintered.
