PELLETS INCORPORATED WITH CARBONACEOUS MATERIAL AND METHOD OF PRODUCING REDUCED IRON |
摘要 |
Pellets incorporated with a carbonaceous material of the present invention contain a carbonaceous material and iron ore mainly composed of iron oxide. The maximum fluidity of the carbonaceous material in softening and melting, and the ratio of iron oxide particles of 10 .mu.m or smaller in the iron ore are within the range above a line which connects in turn points A, H and C shown in Fig. 1, including the line. This permits the production of pellets incorporated with a carbonaceous material having excellent thermal conductivity and high strength. Reduction of the pellets incorporated with a carbonaceous material produces reduced iron having high strength after reduction and a low fines ratio with improved productivity.
