Title:

METHOD FOR ADJUSTING PRECURSOR POWDER FOR SINTERED ORE, AND PRECURSOR POWDER FOR SINTERED ORE

Document Type and Number:

WIPO Patent Application WO/2013/140809

Kind Code:

A8

Abstract:

According to the present invention, by adjusting a mixing ratio [(C/F) × 100] between the mass of an iron ore raw material (F) having particles with a diameter of at least 3 mm, and the mass of coke breeze (C) having particles with a diameter of at least 3 mm, to a range of two to three percent, a precursor powder for sintered ore, which is excellent for efficiently producing sintered ore, can be adjusted, without depending on the quality of the iron ore.
