ABSTRACT OF THE DISCLOSURE A process for producing carbon fibers which comprises feeding an inert gas into a vertical furnace at about 500 to about 1,000°C and into a transverse furnace at about 800 to about 2,000°C connected thereto so that the inert gas flows from the transverse furnace toward the bottom of the vertical furnace and then to the top of the vertical furnace, and feeding pre-oxidized fibers from the top of the vertical furnace to pass the fibers countercurrent to the inert gas flow through the two furnaces to thereby carbonize the fibers. An apparatus is shown in the drawing for the production of carbon fibers by the above process. Carbon fibers having good performance can be produced with good efficiency.
