[0002] The raw materials of aluminum strips are pure aluminum or aluminum alloy casting and rolling aluminum coils, hot-rolled aluminum coils, which are rolled into thin aluminum coils with different thicknesses and widths by a cold rolling mill, and then longitudinally cut into aluminum strips with different widths by a slitting machine according to the use. During the production process of aluminum strips, a casting and rolling machine is required, and the processing of aluminum strips is realized through the casting and rolling rolls arranged inside the casting and rolling machine. The roll consists of a roll body and a roll core.

[0003] In some existing rolls, the roll body and the roll core are integrally arranged. When the roll body is damaged, it needs to be replaced as a whole, which may cause some material losses and reduce the material utilization rate. Therefore, in order to solve the above problems, we propose a casting and rolling roll for aluminum material casting and rolling. Content of the Utility Model
