The liquid phase flow characteristic of iron ore directly impacts the pore structure. If the ore has a poor melt characteristic, it is difficult to form a liquid phase. As a result, the internal porosity of the sintered ore is quite high and such sintered ores are usually of low strength (Ni et al., 2020). The traditional method of studying ...
