[0002] High modulus carbon fiber needs to undergo high-temperature graphitization treatment at 2200-3000℃. Its tensile modulus increases with the increase of treatment temperature. The preparation of high modulus carbon fiber is inseparable from the continuous ultra-high temperature graphitization furnace. As the design temperature of the continuous ultra-high temperature graphitization furnace increases, the ablation characteristics of the material at ultra-high temperature are of great significance to the selection of the furnace chamber and electrode materials of the continuous graphitization furnace. The ultra-high temperature materials reported so far only have data at specific temperatures, and the data from different sources have great deviations. The current ultra-high temperature material testing has not formed a systematic testing device, and non-professional testing devices cannot work continuously for a long time at ultra-high temperatures.

In view of this, it is necessary to design a test system for the ablation characteristics of ultra-high temperature materials to solve the above problems. Utility Model Content
