Continuous Carbonization Furnace for Carbon Fiber

Production Mode: Fully automatic Roll-to-Roll continuous operation, supporting 24/7 uninterrupted production, meeting industrial-scale requirements with an annual output of over one thousand tons. Core Temperature Range: Covers temperatures from 600°C to 1900°C (carbonization section) and up to 2800°C (graphitization section). Multiple temperature zones with independent closed-loop temperature control ensure high consistency of fiber properties. Technical Highlights: Utilizes high-precision closed-loop tension control with linkage, equipped with a labyrinth-type oxygen-excluding sealing device and the latest IGBT silent power supply, achieving high yield and damage-free continuous processing of thin fabrics or tows.

Product details

Overview

Yuanhang Continuous Carbonization Furnace for Carbon Fiber is a large-scale production line developed for polyacrylonitrile (PAN)-based, pitch-based, viscose-based fibers, and fuel cell carbon paper. By precisely controlling the fiber travel speed and temperature field gradient, this production line facilitates the chemical transformation of materials under a controlled atmosphere. The equipment integrates an advanced adaptive tension system, solving the industry challenges of easy breakage and wrinkling of flexible materials during continuous processing. It is a core piece of equipment for achieving domestic substitution in high-end carbon material production.
