Description

technical field [0001] The invention belongs to the technical field of metallurgy and chemical industry, and in particular relates to a blast furnace coal injection-iron ore sintering experiment simulation device. Background technique [0002] The behavior of blast furnace injection coal in the blast furnace and the quality of sinter will directly affect the coal coke replacement ratio, the stability of the blast furnace, and then affect the cost of pig iron. Therefore, the combustion characteristics of PCI coal and the quality of sinter have a very important influence on ironmaking production. At present, most of the research in this area is carried out in the laboratory. The existing blast furnace coal injection simulation experimental device and iron ore sintering simulation experimental device occupy a large area, are inconvenient to move and are relatively expensive, and the atmosphere in the experimental device is difficult to control. So far, there is no The equipmen...
