[0002] A smelting furnace is a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then smelts them into the required alloy through operations such as slagging and refining.

[0003] However, the existing refined aluminum liquid needs to be manually refined in front of the molten pool with a steel pipe. Since the temperature in front of the molten pool is too high, it not only increases the labor intensity of the workers but also poses great dangers. It is also impossible to spray the refining agent evenly to all parts of the aluminum liquid. In addition, the artificial use of iron pipes as powder spraying refining pipes for smelting cannot ensure full coverage in the molten pool. Because the furnace mouth is small and needs to be moved back and forth, there will be dead corners and places that cannot be covered, which affects the quality of refining and increases the refining time. In view of this, an automatic adjustment device for the powder spraying pipe of a refining furnace machine is proposed to solve the above problems. Utility Model Content
