At the same time, sintered ore is formed by mixing various powdered iron-containing raw materials with appropriate amounts of fuel and flux, adding appropriate amounts of water, and then causing a series of physical and chemical changes in the materials on the sintering equipment after mixing and balling. The process of bonding the ore powder particles into blocks follows the sampling and sample preparation method requirements for the physical test of sintered ore pellets. The samples of sintered ore and pellets need to be subjected to particle size measurement, drum strength measurement, chemical analysis sample preparation, and low-temperature reduction sample preparation.
