Title:
焼結鉱の製造方法
Document Type and Number:
Japanese Patent JP4528362
Kind Code:
B2
Abstract:
Disclosed is a sintered ore manufacturing method, in which a chalybeate starting material that contains multiple brands of iron ore, auxiliary materials, solid fuel, and return ore are blended as a sintering starting material, these sintering starting materials are blended and pelletized, and then charged into a sintering pallet and sintered. Iron ores of high melt permeability, that are selected from the multiple brands or blended so that weighted average of the melt permeability distance is 4.0 mm or greater based on the melt permeability distance measured for each of the brands of the iron ore, are charged to the upper layer, in which the layer thickness proportion is in the range of 5-12% relative to the total layer thickness from the top surface of the starting material fill layer formed on the sintering pallet, and the other iron ores are charged to the lower layer of the starting material fill layer, and auxiliary materials, the solid fuel, and the return ore are charged to the upper layer and the lower layer of the starting material fill layer.
