OXIDATION FURNACE
The invention relates to an oxidation furnace for the oxidative treatment of fibers, in particular for producing carbon fibers, comprising a housing (12), which is gas-tight, apart from passage areas (18, 20) for the fibers (22), and a process chamber (28) located in the interior (14) of the housing (12). By means of an atmosphere device (38, 40, 46), a hot working atmosphere can be produced and blown into the process chamber (28). Deflecting rollers (34), which are arranged outside of the process chamber (28) in deflecting areas (30, 32), guide the fibers (22) through the process chamber (28) in a serpentine manner in such a way that the fibers lie next to one another as a fiber carpet (22a), wherein the fiber carpet (22a) spans a plane between opposite deflecting rollers (34). Outlet fiber carpets (50a) of outlet fibers (50) that have left the process chamber (28) and are on the way to a deflecting roller (34) can be cooled in a specific manner by means of a fiber-cooling device (54) before said outlet fiber carpets reach the deflecting roller (34).
