Zusammenfassung:	The utility model discloses a wear-resistant ceramic metal tube. INCLUDING CERAMIC METAL INNER TUBE, one end of the ceramic metal inner pipe is sleeved with a second fixing ring; the other end is sleeved with a first fixing ring; the first fixing ring and the second fixing ring are fixedly connected with the tail end of the ceramic metal inner pipe; the ceramic metal inner pipe is sleeved with a plurality of annular bases coaxial with the ceramic metal inner pipe, the tops of the annular bases are flush with the top faces of the second fixing ring and the first fixing ring, and a plurality ofheat insulation cavities are annularly formed in the opposite surfaces of the second fixing ring and the first fixing ring and the same side face of each annular base at intervals. A plurality of insertion holes are formed in the side surfaces, close to the first fixing ring, of the annular seat and the second fixing ring; when the ceramic metal inner pipe is used, the arranged heat insulation cavity can effectively condu
