Anode assembly produced by Henan Chalco is the conductor used to connect anode busbar and anode steel claw in aluminum electrolysis process.Conventional Anode assembly is made by adding less than 0.5%Mg element to 99.7% aluminum solution.Guide the average tensile strength is 81.5 Mpa, conductivity is 57.2 % IACS, vickers hardness is 31.1 HV5, in use process due to the low strength and hardness, the high temperature, corrosion, replacing the anode work vigorously to improve the effect of job characteristics, easy to appear the phenomenon such as bending, surface scratch, Anode assembly and anode busbar poor contact, fixture pressure drop is higher, guide maintenance is frequent, service life is short, workers labor intensity and so on.


Manufacturing method of aluminum alloy Anode assembly with high strength and high conductivity in Henan Chalco, including the following steps:
Step 1: aluminum ingots for electrolysis or remelting with purity of 99.6%, magnesium ingots with purity of 99.9% and al-5ti-b alloy rods were selected as raw materials.
Step 2: heat and melt the aluminum ingots to 780 ~ 800℃ in the melting furnace or directly inject the electrolytic primary aluminum at a temperature of 780 ~ 800℃, add magnesium ingots accounting for 0.7-0.8% of the total weight of the raw materials, stir and melt the aluminum alloy liquid, and then add the coating agent after refining and degassing;
Step 3: to aluminum alloy liquid temperature control during 730 ~ 740 ℃, the liquid aluminum alloy imported pouring shaft, according to the casting speed with thread feeding machine add Φ 9.5 millimeters in diameter in chute ti Al - 5 - B alloy rod online grain refining process for aluminum alloy liquid;
The fourth step: according to the requirements of casting blank chamfering, milling, punching and other mechanical processing to get qualified Anode assembly.
