Through the arrangement of the flow equalization groove 304, the molten aluminum is first blocked by the flow guide column 306, and the molten aluminum is distributed, a part of the molten aluminum enters the inner wall of the flow guide groove 307 and is transported to one end of the movable frame 308 with the rotation of the flow guide groove 307, thereby achieving the purpose of uniformly distributing the molten aluminum, and at the same time, the reciprocating movement of the flow guide column 306 and the flow guide groove 307 makes the distribution of the molten aluminum more uniform, and then the molten aluminum penetrates the reciprocating movable frame 308 and the flow distribution plate 309, further improving the uniformity of the molten aluminum distribution, thereby achieving the purpose of uniformly distributing the molten aluminum and improving the quality of the aluminum alloy slab;

[0054] Through setting the second ball 416, the blocking strip 417 and the driving groove 414, the second ball 416 is in contact with the driving groove 414 rarely, and the efficiency of heat transfer from the second driving column 402 to the driving pipe 415 is poor. One end of the driving pipe 415 is connected to the air source, so that the air passes through the gap between the second ball 416 and the driving groove 414 and cools the inside of the driving pipe 415 and the second ball 416, preventing the driving pipe 415 and the second ball 416 from being damaged due to high temperature. Through setting the ball seat 406 and the first ball 407, the first ball 407 has a small contact area with the first fixed ring 404, so that the heat transfer efficiency of the driving frame 405 and the first fixed ring 404 is low, avoiding damage to the driving frame 405. The driving frame 405 is matched with the first ball 407 through the ball seat 406, so that the driving frame 405 can keep relatively static with the third driving column 403 in the horizontal direction, that is, the driving frame 405 can drive the first fixed ring 404 to move back and forth, and the generated airflow can cool the first ball 407. Through setting the guide sleeve 424 and the guide column 425, the movement of the driving frame 405 can be guided. Through setting the plug 311, and the plug 311 is embedded in the middle of the side sealing plate 301 at both ends of the movable frame 308, so that the movable frame 308 moves back and forth, driving the plug 311 to move, and preventing the aluminum liquid from entering the middle of the side sealing plate 301.
