MAKING METHOD OF ORE SINTERING

摘要

The sintering material mixed with a coke as powder source material forms upper and lower layers in sintering machine. The upper layer covering 10-40% in thickness includes an anthracite coal having high heat quantity instead of the coke as the power source material. The lower layer covering 60-90% in thickness includes the coke as the power source material. The sintered ore is excellent in quality.
