6082 alloy aluminum sheet smelting process
1. Smelting
6082 alloy is characterized by containing Mn, Mn is a refractory metal, the melting temperature should be controlled at 740-760 ℃. Stir more than twice before sampling to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform. After stirring, take a sample in 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 a static furnace, it is sprayed with nitrogen and a refining agent for spraying and jet refining. The refining temperature is 735-745°C for 15 minutes. After refining, it is allowed to stand for 30 minutes. Through this process degassing, slag removal, and purification of the melt.
During the casting process, there are two filtering devices between the casting mold and the furnace port. The furnace port has a foam ceramic filter plate (30PPI) for filtering. Before casting, it is filtered with 14 mesh glass fiber wire cloth to fully filter out the oxides and slag inclusions in the melt.
The casting temperature of 6082 alloy aluminum plate is high (compared to the normal process of 6063 aluminum plate), the casting speed is low, and the water flow is large. The above process needs to be strictly controlled and cannot exceed the range, otherwise it will easily lead to casting failure.
Heat treatment process of 6082 aluminum plate
Melting 6082 alloy is characterized by containing Mn, which is a refractory metal, and the melting temperature should be controlled at 740-760℃. 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 in the middle of the molten aluminum depth and on the left and right sides of the furnace for analysis, and the converter can be converted after the analysis is qualified.
Purification and casting After the melt is transferred to the static furnace, it is sprayed with nitrogen and refining agent and refined by air jet. The refining temperature is 735-745°C for 15 minutes. After the refining, it is allowed to stand for 30 minutes. Through this process, degassing, slag removal, and melt purification. There are two filtering devices between the mold and the furnace mouth during casting. 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 relatively high (compared with the normal process of 6063 aluminum plate), the casting speed is relatively low, and the water flow is relatively large. The above process needs to be strictly controlled and cannot exceed the range, otherwise it will easily lead to casting failure.
Applications for 6082 Aluminum Sheet
Aviation fixtures, trucks, towers, ships, pipelines and other construction applications where strength, weldability and corrosion resistance are required. Such as: aircraft parts, camera lenses, couplers, marine accessories and hardware, electronic accessories and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, car fuel tank, traffic vehicles, valves and valve parts etc
With the rapid development of the shipbuilding industry at home and abroad, reducing the weight of the hull, increasing the speed of the ship, and seeking to replace aluminum alloy materials with steel parts, it has become an important issue facing the aluminum processing industry and the shipbuilding industry. 6082 aluminum sheet’s high quality and light weight make it an ideal material for high-speed ship components.
- Good formability, weldability, machinability and corrosion resistance;
- 6082 Aluminum Sheet with moderate strength, after the annealing can still maintain a good operability;
- Good anode reaction performance, the most commonly used anode reaction methods include the removal of impurities and dyeing, coating and so on;
