Red mud is refinedA by-product of steel, which consists essentially of Fe2O3And a small amount of CaO, and has the characteristics of fine granularity, good cohesiveness and high iron content. In order to utilize the byproduct red mud, the byproduct red mud is often transported to a sintering chamber and poured into a sintering return ore bin to be used as an iron-containing raw material to be added together with return ores, so that the waste water generated in the steelmaking process can be consumed, and the dust can be reduced by adding water into iron materials and the return ores in a feeding field. However, the red mud is not as sparse as we imagine, and is often extremely viscous, when the red mud pump is stopped, the viscous red mud in the pipeline can be attached to the inner wall of the red mud pipeline, the more the viscous red mud is gathered, the red mud pipeline can be blocked finally after a long time, and particularly, the probability of pipeline blockage is higher when the temperature is reduced in winter. The work of dredging the pipeline is more complicated and blind, because it is unknown which section of pipeline is blocked, the pipeline is drilled everywhere, and the sprayed red mud is difficult to clean the pollution of the operation field, and the problem of solving the defect is particularly important from the viewpoint of equipment maintenance and environmental protection.
