Description

Technical Field

[0001] This utility model relates to the technical field of aluminum-magnesium alloy smelting equipment, specifically to an aluminum-magnesium alloy smelting device with a high-efficiency degassing structure. Background Technology

[0002] Aluminum-magnesium alloys are widely used in aerospace, transportation, and 3C products due to their low density, high specific strength, and good corrosion resistance. Aluminum-magnesium alloys are typically manufactured using die casting, which requires initial melting. This melting process involves mixing aluminum, magnesium, and other alloying elements at 700-750℃. The resulting alloy contains gases, which can cause porosity in the finished casting, affecting its usability. However, traditional aluminum-magnesium alloy smelting equipment mostly adopts a single-stage graphite rotor degassing structure. The rotor is inserted into the molten alloy liquid and rotates. The gas is only stirred by the rotor to make it float, which takes a long time and has low production efficiency. Utility Model Content

[0028] In summary, the aluminum-magnesium alloy smelting device with a high-efficiency degassing structure provided by this utility model allows the sealing and stirring mechanism 7 to move downwards via the telescopic cylinder 6 during operation. At this time, the sealing cover 72 can cover the furnace body 4, and the pressure of the telescopic cylinder 6 can seal the top opening of the furnace body 4 with the sealing cover 72. At this time, the vacuum pump 105 can evacuate the inside of the furnace body 4, thereby quickly expelling the gas in the magnesium alloy solution inside the furnace body 4. Simultaneously, the operation of the motor 75 can rotate the transmission rod 76, which can stir the solution inside the furnace body 4 with the stirring rod 77, thereby improving the gas expulsion efficiency inside the magnesium alloy solution. During vacuuming, when the gas passes through the inclined tube 102, it will condense into liquid magnesium upon contact with the cooler inner wall of the inclined tube 102. The liquid magnesium will flow along the inclined tube 102 into the connecting pipe 103 and finally fall into the collection tank 12. This structure allows for the recovery of liquid magnesium and reduces the magnesium loss rate.
