PRODUCTION METHOD OF SINTERED ORE

摘要

PROBLEM TO BE SOLVED: To provide a production method of sintered ore by which decrease in productivity and rise in production cost caused by change in property of coke breeze and anthracite as a coagulation material, and change or the like in particle size composition accompanying the change can be suppressed.SOLUTION: Before and after a brand and/or a ratio of a carbonaceous material included in a coagulation material is changed, calorific power derived from particles of a particle diameter of at most 1 mm of the coagulation material after the change is maintained same as calorific power derived from particles of a particle diameter of at most 1 mm before the change. It is desirable that deterioration in a basic unit of the coagulation material is suppressed while calorific powers derived from particles of a particle diameter of at most 1 mm before and after the change are maintained to become same by adjusting a particle ratio of particles of a particle diameter of at most 1 mm of the coagulation material.
