Abstract (en)
1. A method for continuously producing carbon fiber which comprises (1) using a horizontal calcining furnace comprising (i) a heating chamber comprising an inlet introducing fiber to be carbonized and an outlet for carbon fiber produced, at least one inlet introducing an inert gas, and at least one outlet discharging decomposition gas formed from calcining the fiber in the heating chamber, and (ii) at least one gas sealing chamber which is provided at at least one of the fiber inlet and the fiber outlet to and from the heating chamber, and said sealing chamber further comprising an inlet introducing an inert gas; and (2) maintaining pressure within the sealing chamber at a pressure value greater than each of the pressure within the heating chamber and atmospheric pressure. <IMAGE>
