Document Type and Number:
Japanese Patent JP6671779
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method that simply and accurately determines blending of materials of sinter, which does not degrade the productivity of the sinter while reusing a lot of scale powder.SOLUTION: A combination and a ratio of materials in a test preliminary granulation step and a test production granulation step where a melt penetration distance D relating to a test piece 10 formed by sintering a tablet 10A formed of a first nucleus 11 obtained in a test stage and formed according to a test preliminary granulation step, and a first coating part 12 formed by adhering iron ore, an auxiliary material or the like and a carbonaceous material to a circumference of the first nucleus 11 according to a granulation step becomes shorter than a predetermined length are adopted in a combination and a ratio of materials in a production preliminary granulation step and a production granulation step relating to a sinter formed by sintering a granulated material formed a second coating part formed by adhering iron ore, an auxiliary material or the like and a carbonaceous material in the surroundings of a second nucleus by a production granulation step in the production step.SELECTED DRAWING: Figure 4
