METHOD FOR MANUFACTURING PSEUDO-PARTICLES FOR SINTERED ORE MANUFACTURE, AND METHOD FOR MANUFACTURING SINTERED ORE

WIPO Patent Application WO/2013/145332

A1

[Problem] To provide pseudo-particles used for sintered ore manufacture and a method for manufacturing sintered ore that are effective at improving sintered ore production efficiency by improving the ventilation of a raw-material fill layer when operating a sintering machine, without promoting a decrease in strength or yield. [Solution] A method for manufacturing the pseudo-particles and manufacturing sintered ore using the pseudo-particles by, when manufacturing pseudo-particles for sintering raw material by adding an amount of water to and pelletizing the sintering raw materials, adding an amount of water to the sintering raw material that is an excessive amount of water compared with the appropriate amount of water and then pelletizing the raw material, forming pseudo-particles having a larger grain size than the grain size that is formed with the appropriate amount of water, drying the pseudo-particles, and then reducing the amount of water after drying to near the appropriate amount of water.
