Abstract

PURPOSE: To improve low-temperature reduction degradation properties of sintered ore by gradually cooling it for a specified period of time within the specified temperature range when it is cooled after sintering reaction.
CONSTITUTION: In production process of sintered iron ore using a sintering machine, it is graudally cooled in the cooling process so that the temperature range of 300W700°C is maintained for one minute or more. This gradual cooling is simply done by stopping forced draft or reducing the draft quantity in the temperature range of 300W700°C without modifying the existing sintering machine.
