Problems solved by technology

At present, the high-strength and high-conductivity aluminum alloy thick-walled pipes used in the protection of power equipment and facilities play a vital role in the protection of high-voltage wires and cables. At present, 6063 alloy is mostly used for high-strength and high-conductivity conductors. The strength of 6063 alloy is lower than that of 6082 alloy. Although 6082 alloy has high strength, it is not suitable for online quenching due to its high degree of alloying and high quenching sensitivity, and its strength decreases during online quenching. , Corrosion resistance deteriorates. Although off-line quenching can increase the strength of the alloy, the production efficiency and yield rate are reduced. How to produce 6082 alloy high-strength and high-conductivity thick-walled pipes through on-line quenching, so that it has high strength, good plasticity, high specific strength, High electrical conductivity, high thermal conductivity, good corrosion resistance, no tendency to stress corrosion cracking, strong resistance to intergranular corrosion, good welding performance, constant corrosion resistance in the welding zone, good machinability, etc., suitable for various forms of Surface oxidation and anti-corrosion treatment, maintaining good performance in the environment of atmospheric acid-base, high cold, high heat, humidity, drought, wind and sand, is the problem to be solved by the present invention
