APPARATUS FOR USE IN THE PRODUCTION OF GRAPHITE FIBERS |
摘要 |
A vertical heating apparatus for production of graphite fibers from preoxidized fibers or carbon fibers comprises of a tubular heating element which generates heat by high frequency induction. A heat-insulating material layer surrounds the tubular heating element coaxially. The layer is composed of carbon particles having specific grain diameters and angles of repose. A high frequency induction unit is provided around the heat-insulating material layer also in a coaxial relation thereof. |
