Abstract
A furnace for the thermal treatment, particularly for carbonization and/or graphitization, of material, particularly of fibers, particularly of fibers made from oxidized polyacrylonitrile (PAN), the furnace having a furnace housing and a process chamber located in the interior chamber of the furnace housing, which is delimited by a process chamber housing and into which the material to be treated can be introduced. A process chamber atmosphere prevailing in the process chamber can be heated by means of a heating system. An insulation layer thermally insulates the process chamber. The insulation layer is an insulation fill made from a solid particulate material.
Claims16
A furnace for the thermal treatment of fibers, comprising:
- a) a furnace housing;
- b) a process space which is located in the interior space of the furnace housing and is delimited by a process space housing and into which the material to be treated can be introduced;
- c) a heating system by means of which a process space atmosphere present in the process space can be heated;
- d) an insulation layer which thermally insulates the process space, wherein
- e) the insulation layer is an insulating bed composed of a solid particulate material.
The furnace as claimed in claim 5, wherein the carbon black material is a gas black, a furnace black, a flame black, a carbon black from cracking, an acetylene black, a thermal black, a channel black or a mixture of a plurality of these types of carbon black.
