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.
