PROBLEM TO BE SOLVED: To provide an apparatus and method for producing a pitch-based short carbon fiber, more specifically, an apparatus and method for drawing an ejected pitch using melt spinning to produce carbon fibers as short fibers in a continuous manner.SOLUTION: According to an embodiment of the present invention, an isotropic pitch is maximally drawn by a rotation force of the roll, thereby maximizing mechanical strength of a pitch precursor. Also, according to an embodiment of the present invention, a pitch fiber which is being spun can be cut in a short state, thereby resolving a fiber breakage problem. Furthermore, according to an embodiment of the present invention, the pitch fiber which is being spun can be arranged in one direction without using separate additional processes, and be transformed into a carbon fiber with excellent strength through a non-embodiment process and/or a carbonization process. By adopting the effects as above, the carbon fiber using an isotropic pitch as a raw material can replace a high cost PAN or an anisotropic pitch-based carbon fiber. |
