Embodiment 1
[0018] A method for manufacturing an aluminum alloy sacrificial anode suitable for Bohai Bay sea mud. Weigh 2.5% zinc; 0.01% indium; 0.08% tin; 4% magnesium; 0.12% lanthanum; 0.12% actinium; 0.03% cerium; 0.04% silicon, 93.1% aluminum.
[0019] Wrap indium, tin, magnesium, lanthanum, actinium, and cerium with aluminum foil, put them into the molten aluminum, and then put zinc into the molten aluminum. After the alloy is completely melted, check that the impurity silicon content is 0.04%; The molten alloy is poured into a mold and cast into an aluminum alloy sacrificial anode body. The weight of the aluminum foil is included in the component aluminum.
[0020] refer to figure 1 . The aluminum alloy sacrificial anode body includes a sacrificial anode 1 and a connecting plate 2. The sacrificial anode 1 is a semi-circular cylinder, that is, the cross section of the sacrificial anode 1 is a semi-circular ring, and two semi-circular sacrificial anodes 1 are opposite to form a hol...
Embodiment 2
[0025] A method for manufacturing an aluminum alloy sacrificial anode suitable for Bohai Bay sea mud. Weigh 4% zinc; 0.05% indium; 0.05% tin; 6% magnesium; 0.2% lanthanum; 0.2% actinium; 0.03% cerium, 89.44% aluminum; 0.03% silicon. Lanthanum, actinium and cerium are products of Baotou Iron and Steel (Group) Co., Ltd.
[0026] Alloy indium, tin, magnesium, lanthanum, actinium, and cerium, press the alloy into the molten aluminum, and then put zinc into the aluminum melt. After the alloy is completely melted, check that the silicon is 0.03%; The molten alloy is poured into a mold and cast into an aluminum alloy sacrificial anode body.
[0027] The aluminum alloy sacrificial anode body includes a sacrificial anode 1 and a connecting plate 2. The sacrificial anode 1 is a semi-circular cylinder, that is, the cross section of the sacrificial anode 1 is a semi-circular ring, and two semi-circular sacrificial anodes 1 are opposite to form a hollow cylinder. The inner diameter of th...
Embodiment 3
[0032] A method for manufacturing an aluminum alloy sacrificial anode material suitable for Bohai Bay sea mud. Weigh 5% zinc; 0.03% indium; 0.02% tin; 8% magnesium; 0.29% lanthanum; 0.30% actinium; 0.04% cerium, 86.27% aluminum; silicon content 0.05% . Lanthanum, actinium and cerium are products of Baotou Iron and Steel (Group) Co., Ltd.
[0033] Alloy indium, tin, magnesium, lanthanum, actinium, and cerium, press the alloy into the molten aluminum, and then put zinc into the aluminum melt. After the alloy is completely melted, check that the silicon is 0.05%; The molten alloy is poured into a mold and cast into an aluminum alloy sacrificial anode body. The weight of the aluminum foil is included in the component aluminum.
[0034]The aluminum alloy sacrificial anode body includes a sacrificial anode 1 and a connecting plate 2. The sacrificial anode 1 is a semi-circular cylinder, that is, the cross section of the sacrificial anode 1 is a semi-circular ring, and two semi-cir...
