[0002] In order to remove impurities in isostatic graphite, it is necessary to purify the isostatic graphite to meet higher usage requirements. During the purification process of isostatic graphite, the isostatic graphite can be placed in a high-temperature atmosphere furnace, and then purified gas is introduced to purify the isostatic graphite, and finally the isostatic graphite is taken out.

[0003] In the prior art, a method for preparing nuclear graphite material is disclosed in a patent application with application number 201410638623.1, in which halogen or halogenated hydrocarbon purification gas is introduced for purification during the roasting process.

After the purification treatment is completed, the door is opened to take out the isostatic graphite. The operation is relatively cumbersome and difficult to adapt to the requirements of the automated production line, which affects the purification processing efficiency of the isostatic graphite.
