Abstract

The invention discloses an aluminum cast rolling efficient cooling device and cooling process. The aluminum cast rolling efficient cooling device comprises a graphite and liquid nitrogen mixing device, a spraying device and a control device with a manual control mode and an automatic control mode. The spraying device comprises an upper nozzle, an upper nozzle base, a lower nozzle and a lower nozzle base; the graphite and liquid nitrogen mixing device comprises a nano graphite discharging device, a mixing box and a liquid nitrogen source; and finally, the upper nozzle gathers one path of nitrogen and one path of liquid nitrogen graphite emulsion, the lower nozzle also gathers one path of nitrogen and one path of liquid nitrogen graphite emulsion, and in addition, a water baffle is further arranged and used for receiving condensate water on the outer wall of a liquid nitrogen related pipeline. The aluminum cast rolling efficient cooling device can be matched with the new process, and metal circulation is accelerated on the premise that the surface quality of a cast-rolled plate is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aluminum casting and rolling production, and in particular relates to a high-efficiency cooling device and cooling process for aluminum casting and rolling. Background technique [0002] As is known, aluminum casting and rolling is a production process in which molten metal is directly rolled into shape by using two rotating casting rolls with a water cooling system as a crystallizer. The temperature of the molten metal before rolling is generally controlled at 680-710°C. During the continuous rolling process, the cooling water in the roll needs to continuously take away the heat to reduce the surface temperature of the roll and maintain a thermal balance state, and the aluminum liquid is in direct contact with the surface of the casting roll, which is easy to stick to the roll, so it is necessary to spray a lubricating medium on the surface of the casting roll To avoid sticking rollers and ensure the qua...
