Continuous Graphitization Furnace

Production Advantage: Designed specifically for self-towing materials such as carbon fiber, graphite paper, and silicon carbide fiber, supporting 24-hour continuous loading and unloading, with production efficiency far exceeding that of traditional batch-type graphitization furnaces. Core Specifications: Maximum temperature of 3000°C. Through ultra-high temperature heat treatment, it promotes the orderly stacking and rearrangement of the hexagonal network structure of carbon atoms, achieving a high degree of graphitization and significantly increasing the internal carbon content. Intelligent Integration: Equipped with high-precision imported infrared temperature measurement and the latest IGBT constant current power supply. Built-in air curtain isolation system and internal circulating pure water cooling ensure atmosphere purity and equipment stability during continuous operation.

Product details

产品简介 / Introduction

Yuanhang Continuous Graphitization Furnace is primarily used for various flexible carbon materials under inert atmosphere protection, continuously passing through a high-temperature zone of 2000-3000°C. During this process, the microscopic hexagonal network structure of the material begins to rearrange and grow toward a planar grid, forming orderly stacked graphite crystals. This equipment is particularly suitable for high-modulus pitch-based carbon fibers, vapor-grown carbon fibers, graphite paper (flexible graphite), and other materials capable of withstanding certain tension and achieving self-towing. It is an essential tool for the industrial-scale production of high-end carbon materials.

Technical Highlights of Yuanhang Continuous Graphitization Furnace

1.Extreme Process Control: Digital intelligent temperature control supports storage of 20 process curves (totaling 400 segments), fully automated for purging, heating, and cooling.
2.Modular Integrated Design: Power supply, water cooling, and gas protection are highly integrated. Components are clearly marked with serial numbers, supporting remote fault diagnosis and maintenance.
3.Advanced Temperature Measurement System: High-precision infrared pyrometer combined with bidirectional closed-loop PID adjustment ensures minimal temperature field fluctuations during ultra-high temperature continuous operation.
4.Efficient Atmosphere Protection: Features an ultra-low dew point of -70℃, with multi-channel intake and exhaust design, completely eliminating oxidation interference during the graphitization process.
5.Environmental Protection & Energy Saving: Utilizes a true internal circulating pure water cooling and dust-proof design, reducing harmonic interference (IGBT power supply) and protecting other instruments in the workshop.
