摘要： A method for producing carbon fibers in a vertical carbonizing furnace and an apparatus for producing carbon fibers using such a method are disclosed. The furnace includes a heating chamber for carbonizing fibers, the furnace including,(i) a fiber inlet at the upper end of the chamber(ii) an air tight sealed fiber outlet at the lower end of the furnace,(iii) an inert gas inlet provided on the wall of the chamber and above the fiber outlet,(iv) at least one inert gas injection portion, formed on the wall of the chamber, each capable of forming a curtain of inert gas across the heating chamber, each injection portion being provided between the gas inlet and the fiber inlet,(v) at least one outlet each being provided below each inert gas injection portion, and(vi) a heating member capable of controlling the temperature in the heating chamber in such a manner that the temperature gradually increases from the upper end toward a lower end of the heating chamber. The carbon fibers produced by this method or apparatus are excellent in that they have few fluffs and cohering filaments and improved strength and ductility.
