[0032] The preparation method of the aluminum alloy sacrificial anode material comprises the following steps:
[0033] 1) During the whole process of continuously feeding inert gas for protection, the aluminum ingot with a purity of 99.99% is put into a graphite crucible for melting, and the temperature is raised to a predetermined temperature to completely melt it to obtain molten aluminum;
[0034] 2) After melting and heat preservation for 30~35 minutes, add Zn to the molten aluminum according to the ratio, melt and stir evenly, then add other alloying elements In, Mg and Sn in turn until completely melted, stir gently, then remove slag, and keep warm;
[0035] 3) Finally, cast into a mold and cool to room temperature, so as to prepare the aluminum alloy casting.
[0036] In step (1), the inert gas is nitrogen. The melting temperature is 770°C to 790°C.
[0037] In step (2), the holding time after slag removal is 2-2.5 hours.
[0038] In step (3), the pouring temperature...
Embodiment 1
[0040]First put high-purity aluminum ingots (purity 99.99%) into a graphite crucible melting furnace, raise the temperature to 780°C to melt it into molten aluminum, and then add 3.7% Zn, 0.03% In, 0.45 % Mg, 0.065% Sn, stir evenly, and keep warm for 30min after the temperature rises to 780°C. Then stir and remove the slag. After fully stirring, keep it warm at 780°C for 2 hours to make it uniform. Finally, the melt is poured into the mold at a pouring temperature of 710°C. After the casting is cooled to room temperature, the aluminum alloy casting can be prepared; during the whole smelting process, an inert gas nitrogen is used to protect the melt to reduce the burning loss of alloying elements. After the smelting is completed, the alloy composition of the sample is detected by inductively coupled plasma emission spectrometer (ICP), and the actual chemical composition is basically the same as the design composition.
Embodiment 2
[0042] First put high-purity aluminum ingots (purity 99.99%) into a graphite crucible melting furnace, raise the temperature to 770°C to melt it into molten aluminum, and then add 3.0% Zn, 0.01% In, 0.4 % Mg, 0.01% Sn, stir evenly, and keep warm for 30min after the temperature rises to 770°C. Then stir and remove the slag. After fully stirring, keep it warm at 770°C for 2.2h to make it uniform. Finally, the melt is poured into the mold, and the pouring temperature is 715°C. After the casting is cooled to room temperature, the aluminum alloy casting can be prepared; during the whole smelting process, an inert gas nitrogen is used to protect the melt to reduce the burning loss of alloying elements. After the smelting is completed, the alloy composition of the sample is detected by inductively coupled plasma emission spectrometer (ICP), and the actual chemical composition is basically the same as the design composition.
