Analysis of production process of aluminum alloy 6082 sheet
Aluminum alloy 6082 plate belongs to 6xxx series (Al-Mg-Si) alloy aluminum plate, which is a kind of aluminum alloy plate that can be strengthened by heat treatment, with medium strength and good welding performance, corrosion resistance, mainly used in transportation and structural engineering industries. Mainly used in the transportation and structural engineering industries, such as bridges, cranes, roof frames, transport vehicles, ships, etc.
The superior performance of 6082 aluminum sheet comes from the precise requirements of its production process. First is melting. The 6082 alloy is characterized by containing Mn. Mn is a refractory metal, and the melting temperature should be controlled at 740-760 °C. Before sampling, it needs to be stirred evenly for more than two times to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform. After stirring, take samples from the left and right sides of the furnace in the middle of the depth of the molten aluminum, and transfer them to the furnace after folding; secondly, in the process of purification and casting, after transferring the melt to the static furnace, spray powder and gas with nitrogen and refining agent The melt is refined, the refining temperature is 735-745 ° C, the time is 15 minutes, and the refining is allowed to stand for 30 minutes. Through this process, gases, slag and smelt are removed. When casting, there are two filter devices between the mold and the furnace mouth. The furnace mouth is filtered by a foam ceramic filter plate (30PPI), and filtered through a 14-mesh glass fiber cloth before casting to fully filter out oxides and slag in the slag. .
