A hermetically sealed container is equipped inside thereof with: a melting furnace; a cooling roll for subjecting the molten metal tapped from the melting furnace to primary cooling to form a casting; and a rotatable cooling drum which receives the casting formed by the cooling roll and which subjects the casting to secondary cooling. The cooling drum has: a tubular member elongated in one longitudinal direction and having a receiving opening which is formed to open on one side of the tubular member to receive therein the casting, and a discharge opening which is formed to open on an opposite side of the tubular member to discharge the casting that has been subjected to the secondary cooling; and a transfer means for transferring the casting received from the receiving opening toward the discharge opening in response to the rotation of the tubular member.

The present invention provides a continuous rolling temperature control process for high-flux continuous casting and direct rolling of a continuous aluminum alloy cast slab, comprising a continuous casting machine, a through-beam laser transmitter K, a controller, a spraying head, and a spraying system. A liquid-state aluminum alloy metal melt passes through the continuous casting machine and then is cooled and solidified to form a continuous cast slab; the movement direction of the continuous cast slab is controlled by a lifting table so that the continuous cast slab passes through an interior of a traction machine and extends into a continuous rolling machine; and the through-beam laser transmitter K is arranged between the continuous casting machine and the traction machine. According to the present invention, comprehensive performance indicators required by different series of aluminum alloys under high-flux continuous casting and direct rolling conditions are distinguished, and the continuous rolling temperatures of continuous cast slabs of different series of high-flux continuous cast and rolled aluminum alloy sheets are correspondingly designed and controlled. A preset continuous rolling temperature enables the comprehensive performance of different series of aluminum alloys to reach a product quality standard, reduces interior defects and alleviates the problems of segregation and the like. The flow velocity (or flow rate) of the spraying system can be controlled to reduce the loss of a cooling liquid (an emulsion), thereby reducing the cost, and achieving the purpose of energy conservation and emission reduction.
