NOVELTY - The utility model claims a low temperature carbonization furnace for carbon fibre production, comprising a furnace bottom shell, a furnace top cover, a hearth assembly, a hearth assembly assembled by a hearth lower shell and a hearth upper shell is set between the furnace bottom shell and the furnace top cover, the hearth lower shell and the hearth upper shell inner wall are respectively jointed with a graphene lower protective plate and a graphene upper protective plate, conducting heat to the temperature generated by the hearth lower shell and the hearth upper shell by the graphene upper protection plate and the graphene lower protection plate, and receiving the waste gas generated by heating the carbon fibre and the tar condensation point, passing through the split furnace body, a hearth assembly, a graphene upper protection plate and a graphene lower protection plate, the hearth assembly is separated, for cleaning the hearth lower shell and the hearth upper shell in the hearth assembly, improving the convenience of the hearth assembly internal condensation point cleaning operation, reducing the time for cleaning the hearth assembly, reducing the influence of the carbon fibre production when cleaning the hearth assembly.
