METHOD FOR MANUFACTURING CARBON FIBER BUNDLE

A method for manufacturing a carbon fiber bundle includes a stabilization process of subjecting an acrylic fiber bundle to a heat treatment within a range of 200° C. to 300° C. in an oxidizing atmosphere; a pre-carbonization process of performing a heat treatment within a range of 300° C. to 1,000° C. using a heat treatment furnace having at least one inert gas supply port on each of an incoming side and an outgoing side of the fiber bundle and at least one exhaust port between the incoming-side and outgoing-side inert gas supply ports, the heat treatment being performed with a temperature of an inert gas supplied being higher on the outgoing side than on the incoming side; and a carbonization process of performing a heat treatment at a temperature of 1,000° C. to 2,000° C. in an inert gas atmosphere, in which from a position at which an atmospheric temperature in the heat treatment furnace is 300° C., the position being closest to the outgoing side in a machine length direction, up to the inert gas supply port on the incoming side, a flow of an inert atmosphere within the heat treatment furnace in the pre-carbonization process consists only of a flow in a parallel flow direction with respect to a travel direction of the fiber bundle in the machine length direction.

Substrate treatment process

In a substrate treatment process, substrates are moved by a transporting device in a transporting direction through a substrate treatment installation having a number of chambers. The substrates are moved by transporting sections of the transporting device driven independently of one another. The transporting sections are driven such that, if substrates dwell temporarily in the transporting section, they are moved back and forth. Stresses in a substrate brought about by differing inputs of heat as a result of both process-induced and malfunction-induced dwell times of the substrate in a chamber are reduced by compensating within the chamber for a structurally brought about input of heat into the substrate, varying periodically over the length of the chamber, during temporary dwelling of the substrate in the chamber by moving the substrate back and forth over at least one period of the heat input by a change of the transporting direction.
