DETAILED DESCRIPTION

[0021] The utility model will be further explained in connection with the drawings and specific embodiments.

[0022] For example, Figures 1-4As shown, an online carbon ash collection device for aluminum alloy casting and rolling includes a rolling mill support 1, an ash collection box 2, and a back plate 3 disposed at one end of the ash collection box 2. A connecting plate 10 is disposed between the ash collection box 2 and the back plate 3. The bottom surfaces of the ash collection box 2, the connecting plate 10, and the back plate 3 are on the same plane. The rolling mill support 1 is fixed to the casting and rolling mill archway 4. An ash collection trough 5 is disposed inside the ash collection box 2. The end of the ash collection trough 5 away from the back plate 3 is open. A scraper 6 is installed inside the ash collection trough 2. The thickness of the ash collection trough 5 is greater than the thickness of the scraper 6. The scraper 6 is made of hard, high-temperature resistant rubber. The extended end of the scraper 6 is located outside the ash collection trough 5.
