The main purpose of the carbon fiber graphitization furnace is to induce the graphitization crystal orientation of fibers, so as to increase the elastic modulus of carbon fibers. The production of carbon fibers is carried out in a high - temperature and sealed graphitization furnace. Both ends of the furnace are sealed with high - purity argon gas. The heating element is made of graphite material. The graphite tube serves as both the furnace tube of the high - temperature furnace and the heating element. The heating temperature generally ranges from 2500℃ to 3000℃.

The graphitization furnace is primarily utilized for high-temperature processing such as graphite powder purification, operating at temperatures up to 3,000°C. It offers high production efficiency and energy-saving performance. Equipped with a real-time temperature monitoring and automatic control system, it enables continuous tracking and adjustment of the furnace temperature.
