Abstract
An oxidation furnace for the oxidative treatment of fibers having a processing chamber which can be found in the interior of a housing; at least one blowing device; at least one suction device; at least one ventilator that circulates the hot air through the blowing device, the processing chamber, and the suction device; and at least one heating device that lies in the flow path of the hot circulated air. Deviating rollers guide the fibers in a serpentine manner through the processing chamber such that the fibers lie next to one another as a carpet, the fiber carpet being stretched between each opposing deviating roller over one plane. The air in the processing chamber crosses the planes over which the fiber carpet is stretched at an angle that differs from 0° and 90° using special means.
Claims9
An oxidation furnace for the oxidative treatment of fibres comprising:
- a) a housing, which is gas-tight with the exception of passage regions for carbon fibres;
- b) a process chamber located in an interior of the housing;
- c) at least one blowing device by which hot air is into the process chamber;
- d) at least one suction device, which sucks the hot air out of the process chamber;
- e) at least one ventilator which circulates the hot air through the blowing device, the process chamber and the suction device;
- f) at least one heating device located in a flow path of the hot air being circulated;
- g) deflection rollers, which guide the carbon fibres in a serpentine manner through the process chamber such that the carbon fibers lie next to one another as a carpet, wherein the carpet stretches over a respective plane between opposing deflection rollers;
- and, wherein,
- h) means are provided, which ensure that the hot air in the process chamber crosses the plane, over which the carpet stretches, at an angle which deviates from 0° and from 90°.
