Method for production of raw material for use in the production of sintered ore

摘要

Disclosed is a method for producing a raw material for use in the production of a sintered ore. The method comprises: a provision step of providing a sintering raw material powder and an iron ore ultrafine powder having an average particle diameter of 10 µm or less; a formation step of adding the iron ore ultrafine powder to the sintering raw material powder in an amount of about 2 to 15 mass% and mixing the two components with each other, thereby forming a sintering raw material particle coated with the ultrafine powder; and molding step of molding the sintering raw material particle.
