[0047] Such as figure 1 Shown is the first embodiment of the production method of the ingot for high-voltage anode aluminum foil, comprising the following steps:
[0048] S10. Put aluminum-containing raw materials into the smelting furnace to flatten to obtain molten aluminum, control the temperature of the molten aluminum at 700°C to 800°C, and stir the molten aluminum to fully mix various raw materials;
[0049] S20. Add the first intermediate alloy to the aluminum liquid described in step S10, and stir at the same time, so that all kinds of raw materials are fully mixed and stirred evenly;
[0050] S30. Pour the uniformly mixed aluminum liquid in step S20 into the holding furnace, and stir at the same time; after all the aluminum liquid is poured into the holding furnace, take samples at two different positions of the holding furnace to detect the composition of the aluminum liquid;
[0051] S40. When the composition of the aluminum liquid sampled and detected at two diffe...
Embodiment 2
[0076] This example is similar to Example 1, the difference is that in this example, the aluminum-containing raw material includes the following components calculated by mass fraction: a, 50wt% segregation refined aluminum; b, 50wt% three Refined aluminum by layer method; c, 0wt% high-precision aluminum waste; in addition, during casting in this embodiment, casting speed V, cooling water flow rate L and molten aluminum temperature follow the change of casting length K in the form of Table 1, as shown in Table 2 Show.
[0077] In Table 2 Example 2, the parameters of casting speed and cooling water flow change with the casting length
[0078]
[0079] When the casting length reaches a certain fixed value (not greater than 500mm), the casting speed and cooling water flow rate will not change, and will be stable at the current value until the casting ends.
[0080] The ingot obtained by casting according to the above-mentioned casting parameters and the steps of Example 1 is p...
Embodiment 3
[0082] This example is similar to Example 1, the difference is that in this example, the aluminum-containing raw material includes the following components calculated by mass fraction: a, 50wt% of segregated refined aluminum; b, 30wt% of three Layer refined aluminum; c, 20wt% high-precision aluminum waste; in addition, during casting in this embodiment, the casting speed V, the cooling water flow rate L and the temperature of the molten aluminum follow the change of the casting length K in the form of Table 1 as shown in Table 3. Show.
[0083] Table 3 The parameter changes of casting speed and cooling water flow rate with the change of casting length in Example 3
[0084]
[0085] When the casting length reaches a certain fixed value (not greater than 500mm), the casting speed and cooling water flow rate will not change, and will be stable at the current value until the casting ends.
[0086] The ingot obtained by casting according to the above-mentioned casting parameter...
