模擬與解析高爐銅冷卻壁之磨耗

In the blast furnace ironmaking process, when the charge particles fall, they continuously impact the cooling staves of the blast furnace body, causing irreversible wear and reducing the service life of the cooling staves. Severe wear and tear may even cause the water channels in the cooling staves to be exposed, causing cooling water to leak and flow into the blast furnace. In the blast furnace, it seriously affects the reaction environment in the furnace; in addition, after the cooling water channel fails, the temperature of the blast furnace wall rises, and the high temperature is also a dangerous load without warning, which even affects the structural safety of the blast furnace. Therefore, it is necessary to reduce the wear of the blast furnace wall. , to maintain the function of blast furnace ironmaking. This project plans to use the discrete element method and wear theory to analyze the wear problem of the blast furnace wall. At the same time, China Steel will establish a charge flow test for the reduced size No. 2 blast furnace, compare the simulation results with the experimental results, and confirm the rationality of the discrete element numerical model. , and then explore the impact of the furnace wall rib type on impact wear, and select the furnace wall rib type with smaller wear as a solution to reduce the wear of the ironmaking blast furnace.
