Embodiment Construction

[0030] Referring to the drawings, numeral 1 denotes an advancing section for fiber material, which is used in a carbonization production line 100 for carbon fiber production.

[0031] A carbonization line is part of a plant for the production of carbon fibres, ie a plant generally comprising a first line or oxidation line and a second line (ie carbonization line 100 ) following the first line.

[0032] The carbonization production line 100 includes one or more carbonization furnaces 101 .

[0033] In the illustrated embodiment, two carbonization furnaces are arranged in series; more precisely, the carbonization production line 100 includes at least a low temperature furnace 102' and a high temperature furnace 102".

[0034] Each carbonization furnace 101 includes at least one furnace 102 operating at at least a predetermined temperature and extending along the advance direction "A" of the fiber material.

[0035] More precisely, the furnace 102 is formed like a substantially ...

Abstract

An advancing part of a fibrous material, the advancing part being used in a carbonization line for the production of carbon fibres, comprising: a support structure (2) extending between two end parts (2a) along the advancing direction (A) of the fibrous material; a plurality of feed rolls (4, 5) for fibrous material, each feed roll being rotatably connected to the support structure (2) via a pair of support elements (8); wherein the inlet roll (4a) and / or the outlet roll The support element (8) of (4b) comprises: a base (8a), the base is integrated with the support structure (2); a support ring (8b), the support ring is connected with the base (8a), and has at least one through the opening, through through openings for receiving one end of a respective feed roller (4a, 4b); and an adjustment device (8c) operatively interposed between the base (8a) and the ring (8b) and configured such that The position of the ring (8b) relative to the base (8a) is moved in an adjustment direction (B), which is preferably substantially vertical.

Description

technical field [0001] The invention relates to an advancing part for fiber material and a carbonization furnace for producing carbon fibres. Accordingly, the invention finds particular application in the treatment of fiber bundles or fabrics, preferably in the production of carbon fibers from precursor fibers. Background technique [0002] It should be noted that the availability of carbon fiber and the possibility of processing it has led to an exponential increase in the use of this composite material in many applications, such as in the energy industry, transportation, civil engineering, the production of sports equipment, and the aviation industry. [0003] Carbon fibers are currently produced by modifying man-made fibers (industrial rayon, experimental lignin), synthetic fibers (polyacrylonitrile, but also PBO and experimentally other thermoplastic fibers) or distillation residues of oils or tars (pitch) Production. The first type of carbon fiber is commonly referred...
