Abstract

PURPOSE: To promote the hardening of psiudo-grains of powdery iron ores and to improve the sintering property of the sintered ores, by forming the pseudo-grains with the addition of a cheap binder to the iron ores having the grain size at which it is difficult to form the pseudo-grains and by piling up at the bedding yard.
