Carbon fiber cracking furnace

The utility model relates to the technical field of energy and chemical industry, in particular to a carbon fiber cracking furnace. Comprising a cracking furnace body, a furnace body support and a power mechanism, the cracking furnace body comprises a cracking barrel and a heating device for heating the cracking barrel, the barrel bottom of the cracking barrel is communicated with a superheated steam leading-in pipe and a waste gas leading-out pipe which are coaxial, and the cracking barrel further comprises a barrel cover; the power mechanism drives the cracking barrel to rotate, so that the cracking barrel is in full contact with the heating device, and the cracking barrel is uniformly heated; the supporting frame provides support for the furnace body so as to keep the axis of the cracking barrel not deviate when the cracking barrel rotates. According to the technical scheme, uniform heating of the cracking barrel can be achieved through the stable transmission mechanism under the constant temperature diffe
