This utility model relates to the field of cement rotary kiln technology and discloses a cement rotary kiln for preventing high-temperature deformation. It includes a base, with a support frame fixedly connected to the inner wall of the base. A fixed chamber is fixedly connected to the outer wall of the support frame.
