[0002] During the smelting process of electric fused corundum, in order to maintain the heat of the high-temperature melt in the furnace, it is usually necessary to add alumina powder into the furnace when the furnace is stopped to form a covering layer to reduce heat loss; when the charge is reheated, due to the large amount of alumina powder added, the material forms a cone-shaped accumulation in the middle of the furnace, making the material layer in the middle too thick; in this case, in order to ensure the thermal insulation of the edge of the molten pool and reduce heat loss, operators usually need to manually scrape the thick material in the middle to evenly distribute it.

[0003] However, this traditional manual scraping method has obvious limitations. First, manual scraping requires workers to exert tremendous physical labor, especially during long working hours, which consumes a lot of physical energy, which not only affects work efficiency, but may also cause work fatigue and health problems. Second, in a high temperature environment, the safety risks of workers are also high.

[0004] Therefore, a device capable of breaking up the molten material in the electric arc furnace so as to make the thickness of the molten material evenly distributed is a problem that needs to be solved. Utility Model Content

[0007] Furthermore, the air outlet pipe of the air bag is connected to the connecting hose through a quick connector, and the connecting hose is connected to the gun barrel through a quick connector.

[0008] Furthermore, the gun barrel includes a horizontal section and a vertical section, and the gun head is detachably connected to the vertical section.

[0009] Furthermore, a connecting portion is provided in the gun head, a vent pipe is provided in the connecting portion, and a connecting rod is connected to the conical tip below the connecting portion, and an air outlet is formed between adjacent connecting rods.
