摘要： The invention relates to a modular furnace, in particular for the oxidative stabilization of a carbon fiber starting material (12), comprising a cuboidal furnace chamber (14), on the upper face (16) of which first deflecting rollers (18) are arranged in a mutually spaced and parallel manner and on the lower face (20) of which second deflecting rollers (22) are arranged in a mutually spaced and parallel manner such that the carbon fiber starting material (12) runs upwards and downwards in a laterally adjacent and slightly spaced manner so as to meander vertically in the area (24) of the furnace chamber (14). A carbon fiber inlet locking device (30) and a carbon fiber outlet locking device (32) are provided on the upper face (16) of the furnace chamber (14), and an air guiding device (44) is connected to the furnace chamber (14). A supply air portion (42) of the air guiding device is connected to a vertical air inlet side (40) of the furnace chamber (14), and a discharge air portion (48) of the air guiding device is fluidically connected to a furnace chamber (14) vertical air outlet side (46) opposite the vertical air inlet side (40). The air guiding device (44) has an air drive device (52) between the supply air portion (42) and the discharge air portion (48).

摘要： A heating device (10) for producing carbon fibers from a thread-shaped fiber starting material (12) is described, wherein the heating device (10) has a central tubular induction heating element (14) through which the fiber starting material (12) is moved, the tubular induction heating element (14) is surrounded by thermal insulation (18), at least one mid- to high-frequency induction coil (22) is provided outside the thermal insulation (18), and an inert gas flows through the central induction heating element (14) in particular for carbonizing and/or graphitizing the fiber starting material (12). For energy optimization, i.e. to achieve an optimal efficiency, a first and a second tube element (26, 28) are provided on the outer side of the thermal insulation (18), said elements are made of material that is transparent to the induction field of the mid- to high-frequency induction coil (22) and are spaced apart from one another by an annular gap (30) through which the inert gas flows.
