[0002] At present, the production equipment of aluminum cast and rolled coils mainly includes a melting furnace, a holding furnace, a front box, a casting and rolling device, and a coiler. The aluminum liquid melted in the melting furnace is poured into the holding furnace, and the aluminum liquid is cooled and kept warm to a suitable temperature in the holding furnace, and then poured into the front box through the holding furnace, and finally rolled into shape by the rollers of the casting and rolling device. After corresponding treatment, it is coiled by the coiler to complete the entire casting and rolling production process.

[0003] Announcement No. (CN216938409U) discloses a holding furnace for aluminum casting and rolling coil production.
