<p>PROBLEM TO BE SOLVED: To provide a charging method to improve yield by segregating more slid fuel such as cokes in the upper brittle layer of a raw material layer for sintering formed on a pallet of a sintering machine. SOLUTION: A ferromagnetic raw material 1 containing iron and a solid fuel 2 are fed to a preliminary pelletizer 14 to form pseudo particles in advance, and a blended raw material in which the pseudo particle raw material is mixed with other raw materials for sintering is stored in an ore feeding hopper. The blended raw material cut out from the ore feeding hopper is charged onto the pallet through a plate-type sloping chute in which a plurality of permanent magnets are arranged in series along the vertical direction on the rear side. Since a larger amount of raw pseudo particle materials consisting of a raw ferromagnetic material containing iron and a solid fuel are segregated in the upper part of the layer of the raw material for sintering formed on the pallet, the sintering property of the upper layer of the raw material for sintering is improved, and the yield and the cold strength of the sintered ore are improved.</p> |
