Smelting process:

1. Smelting The 6082 alloy is characterized by containing Mn, which is a refractory metal, and the melting temperature should be controlled at 740-760 °C. Stir evenly for more than two times before sampling to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform. After stirring, take a sample from the middle of the depth of the molten aluminum and on the left and right sides of the furnace for analysis.

2. Purification and casting After the melt is transferred to the standing furnace, powder spraying and air-jet refining are carried out with nitrogen and refining agent. The refining temperature is 735-745 ℃, and the time is 15 minutes. Through this process degassing, slag removal, and melt purification. During casting, there are two filter devices between the casting mold and the furnace mouth. The furnace mouth is filtered by a foam ceramic filter plate (30PPI). Before casting, it is filtered with a 14-mesh glass fiber cloth to fully filter out the oxides and slag inclusions in the melt.

The casting temperature of 6082 alloy aluminum plate is higher (compared to the normal process of 6063 aluminum plate), the casting speed is lower, and the water flow is too large.
