摘要： A modular furnace, in particular for the oxidative stabilization of a carbon fiber starting material comprising a cuboidal furnace chamber, on the upper face of which first deflecting rollers are arranged in a mutually spaced and parallel manner and on the lower face of which second deflecting rollers are arranged in a mutually spaced and parallel manner such that the carbon fiber starting material runs upwards and downwards in a laterally adjacent and slightly spaced manner so as to meander vertically in the area of the furnace chamber. A carbon fiber inlet locking device and a carbon fiber outlet locking device are provided on the upper face of the furnace chamber, and an air guiding device is connected to the furnace chamber. A supply air portion of the air guiding device is connected to a vertical air inlet side of the furnace chamber, and a discharge air portion of the air guiding device is fluidically connected to a furnace chamber vertical air outlet side opposite the vertical air inlet side. The air guiding device has an air drive device between the supply air portion and the discharge air portion.

摘要： A heating device for producing carbon fibers from a thread-shaped fiber starting material, wherein the heating device has a central tubular induction heating element through which the fiber starting material is moved. The tubular induction heating element is surrounded by thermal insulation. At least one mid- to high-frequency induction coil is provided outside the thermal insulation, and an inert gas flows through the central induction heating element, in particular, for carbonizing and/or graphitizing the fiber starting material. For energy optimization, a first and a second tube element is provided on the outer side of the thermal insulation. The elements are made of material that is transparent to the induction field of the mid- to high-frequency induction coil and are spaced apart from one another by an annular gap through which the inert gas flows.
