Title:
METHOD FOR PRODUCING SINTERED ORE
Document Type and Number:
WIPO Patent Application WO/2024/084749
Kind Code:
A1
Abstract:
Proposed is a method for producing a sintered ore with which it is possible to prevent yield reduction when using a carbon material having a low combustion start temperature. A method for producing a sintered ore that creates a granulated raw material for sintering by granulating a blended sintering raw material containing a carbon material as a solid fuel and sinters the granulated raw material for sintering to obtain a sintered ore, wherein the carbon material is a blend of two or more types of carbon material and is sintered using a blend having a weight average of the sintering start temperature of 550°C or more. Preferably, one with a sintering start temperature of less than 550°C is used as part of the two or more types of carbon materials.
