Abstract: The difficulties of graphite density examination technology were introluced. A graphite density uniformity inspection method based on X-Ray industry computed tomography(ICT) was proposeed. It carried on the average gray level statistics in the round region to the ICT slices and extracted the relative density of the various slices level through data reconstruction of graphite projection, and then evaluated them by 3σ standard. The experiment indicated that it could effectively extract the uniformity level of graphite product interior density and get the accurate judgment of the loose and dense place of the product density.
