Graphite combined type track burning-proof plate

The utility model relates to a graphite combined type track burning-proof plate. The graphite combined type track burning-proof plate comprises a bottom plate made of stainless steel, wherein two sides of the bottom plate respectively have a round hole, and the outer sides of the two round holes are respectively provided with a protective plate, and a mounting groove is arranged in the middle of the bottom plate. The middle of the mounting groove has two through holes, a graphite piece with two through hole in the middle is arranged in the mounting groove, and the positions of the through holes on the graphite piece correspond to the positions of the through holes in the mounting groove. The graphite combined type track burning-proof plate utilizes the low sputtering rate characteristic of graphite materials and easy-processing characteristic of the stainless steel, and designs the combined type track burning-proof plate to meet the requirements of argon ion bombardment resistance of the track burning-proof p
