[0002] There are two main production methods for aluminum sheet bases: hot-rolled slabs followed by cold rolling and cast-rolled slabs followed by cold rolling. The hot rolling process is as follows: aluminum ingot remelting - casting slab - head and tail trimming - milling - slab heating - hot rough rolling - hot finish rolling - cold rolling - tension bending and straightening - finished sheet base.

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] There are mainly two methods for producing aluminum plate base: hot-rolled slab and cold-rolled and cast-rolled slab. The production process of the hot-rolled method is: aluminum ingot remelting-casting ingot slab-cutting head and tail-milling face-ingot slab heating-hot rough rolling-hot finish rolling-cold rolling-bending and straightening-finished plate base, and the production process of the cast-rolled method is: aluminum ingot remelting-continuous casting and rolling-cold rolling-bending and straightening-finished plate base.

[0047] Whether the hot-rolled method or the cast-rolled method is used to produce aluminum plate, the aluminum ingot needs to be remelted. The aluminum ingot remelting method in the prior art is to stack the aluminum ingot in a smelting furnace for high-temperature melting and casting. After the aluminum ingot is stacked, the aluminum ingot is unevenly heated due to the different positions of the aluminum ingots, which causes the slow melting speed of the aluminum ingot and reduces the smelting efficiency of the aluminum ingot.

[0048] Therefore, please refer to Figures 1-4In this embodiment of the invention, a smelting apparatus for continuous casting and rolling of electrolytic aluminum liquid to produce aluminum plates is applied to the smelting of aluminum ingots. Specifically, it remelts aluminum ingots cast from electrolytic aluminum liquid, including a base 1 and a smelting furnace 2 fixedly installed on the base 1. The smelting furnace 2 includes a furnace body 21 and a smelting assembly 7. The smelting assembly 7 is rotatably installed inside the furnace body 21 via a rotating shaft 25. The smelting assembly 7 is provided with a first smelting position 71, a second smelting position 72, and a third smelting position 73 from top to bottom. The first smelting position 71 and the second smelting position 72 are connected, and the second smelting position 72 and the third smelting position 73 are connected. 71 is used to stack aluminum ingots, and the second melting position 72 and the third melting position 73 are used to stack molten aluminum. The first melting position 71 is also connected to the second melting position 72 through at least one first feeding pipe 74. After the aluminum ingot is loaded into the first melting position 71, melting begins. The aluminum ingot gradually changes from solid to liquid aluminum in the first melting position 71. The molten aluminum flows into the second melting position 72 from the feeding pipe 74. The melting assembly 7 is controlled to rotate. The molten aluminum accumulates in the second melting position 72 under the action of centrifugal force. As the molten aluminum continues to increase, the molten aluminum exceeding the storage volume of the second melting position 72 flows into the third melting position 73 and is finally discharged from the third melting position 73.

[0049] like Figure 4 As shown, the first melting position 71 is a funnel-shaped structure with an open top. A first gap is formed between the bottom of the first melting position 71 and the rotating shaft 25. After the aluminum ingot is loaded from the top of the first melting position 71, it accumulates in the first melting position 71. As the melting time increases, the solid aluminum ingot is gradually melted into molten aluminum and flows downward from the first feed pipe 74 and the first gap. The second melting position 72 and the third melting position 73 are both annular structures, and a second gap is formed between the second melting position 72 and the third melting position 73 and the rotating shaft 25.

[0050] Understandably, the aluminum ingots piled up in the first melting station 71 gradually soften as the melting time increases, eventually liquefying into molten aluminum. After the lower layer of aluminum ingots in the first melting station 71 is melted into molten aluminum, it flows from the first feeding pipe 74 into the second melting station 72, and then into the third melting station 73, thereby gradually increasing the amount of molten aluminum at the bottom of the melting assembly 7. At this time, the liquid level of molten aluminum in the melting assembly 7 gradually rises, and the softened aluminum ingots in the first melting station 71 fall down from the gap into the second melting station 72 and the third melting station 73, so that the softened aluminum ingots are submerged in the molten aluminum. During the melting process, the melting assembly 7 drives the movement of molten aluminum and softened aluminum ingots, improving the heating uniformity of the aluminum ingots and avoiding local heating of the aluminum ingots, thereby improving the melting effect of the aluminum ingots.
