Casting roll cooling device for continuous cast-rolling of aluminum sheets

Abstract

The invention provides a casting roll cooling device for continuous cast-rolling of aluminum sheets, and relates to the field of cast-rolling. The casting roll cooling device solves the problems thata main roll body cannot be quickly cooled through the combination of water cooling and air cooling, auxiliary air-blowing cooling cannot be achieved through linkage, and the contact area of the main roll body and water cannot be increased by improving the internal structure of the main roll body. The casting roll cooling device for continuous cast-rolling of the aluminum sheets comprises a frame body, wherein a lower cast-rolling roll structure and an upper cast-rolling roll structure are rotatably connected to the frame body. On one hand, a gear B is installed on a rotary shaft, and is meshedwith a gear A, when the upper cast-rolling roll structure rotates, the rotary shaft and cooling blades are both in a rotary state, and thus wind power heat dissipation can be achieved; and on the other hand, the top end face of an elastic air bottle is in contact with a stirring arm, when the stirring arm follows the main roll body to rotate, the elastic air bottle is in a squeezing state, and thus intermittent air-blowing cooling of the main roll body can be achieved.

Description

technical field [0001] The invention belongs to the technical field of casting and rolling, and relates to a casting roll cooling device for continuous casting and rolling of aluminum plates. Background technique [0002] Casting and rolling is a new process that directly casts and rolls molten metal into semi-finished billets or finished products. The two processes of coagulation and hot rolling are completed between the gaps, and they are completed in a very short time. [0003] The existing casting roll cooling device cannot realize rapid cooling of the main body of the roll through the combination of water cooling and air cooling during cooling; and cannot realize auxiliary air jet cooling through linkage; and the contact area between the main body of the roll and water Not enough cooling effect is not good. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a casting roll cooling device for continuous ca...
