Vorrichtung und Verfahren zur Karbonisierung oder Graphitisierung von Kohlenstoff enthaltenden Fasern oder einem mit Kohlenstoff enthaltenden Fasern gebildeten textilen Gebilde

Abstract

The invention relates to a device for the carbonization or graphitization of carbon-containing fibers, in which fibers are guided through a continuous furnace in which partial pre-carbonization takes place. At least one device which comprises a heating zone and through which the fibers are guided following the achieved partial pre-carbonization is arranged within the continuous furnace or immediately after the continuous furnace. The at least one heating zone is formed by at least one pair of rollers or at least one pair of heating elements which are in electrically conductive contact with fibers, electrical resistance heating of the fibers takes place as a result of the connection of a roller or a heating element to a pole of an electric voltage source and the connection of the respective other roller or the respective other heating element of the pair of rollers or pair of heating elements to the respective other pole of the electric voltage source, and the rollers of a pair of rollers or the heating elements of a pair of heating elements are arranged at a distance from one another, which results in a further carbonization of the fibers
