NOVELTY - The tube has a shell provided with a rotating anode (3) and a cathode (4). A bearing (5) is fixed with the rotating anode. The shell comprises an S-type cathode ceramic section (2) and a metal section (1). Two ends of the cathode ceramic section are respectively provided with annular grooves. The bearing is connected with a baffle plate that is fixed with an end surface of a bearing outer ring. An elastic metal fiber beam (9) is fixed on the shell, where the elastic metal fiber beam bears high temperature of 1000-1100 degree Celsius. USE - Elastic metal fiber and graphene enhanced heat radiation type rotary anode CT ball tube. DETAILED DESCRIPTION - The cathode ceramic section is made of alumina ceramic material. The baffle plate is made of metal molybdenum material. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an elastic metal fiber and graphene enhanced heat radiation type rotary anode CT ball tube.
