I. T-V Synergistic Matching Principle

• Energy Conservation: A unit length of carbon fiber requires absorbing a fixed amount of heat (Q) to be heated from room temperature to the target temperature (e.g., 2200-2800°C). The maximum heating power (P) of the equipment is fixed, so there exists a basic relationship: P = Q × V. This means that given the power, there is a theoretical maximum for the traction speed (V).

• Process Optimization: In actual operation, speed (V) and temperature (T) need to be finely optimized based on fiber specifications (such as tow K-number), precursor type (PAN-based, pitch-based), and target modulus and strength. Increasing temperature allows for适当 higher speeds, but excessively high temperatures or speeds can damage the fibers.

II. Our Technical Solution

• Specialized Equipment: We provide dedicated continuous graphitization furnaces with slender tubular furnace chamber designs, equipped with multi-zone independent temperature control systems capable of forming precise temperature gradient fields.

• Precise Control: The system controls fiber traction speed through high-precision speed-regulating motors, linked with the power output of each temperature zone, ensuring that as the fiber passes through the high-temperature zone, its interior achieves the preset thermal history curve.

III. Application Cases

    We have successfully provided continuous graphitization experimental lines and production pilot lines to multiple research              institutions and high-performance carbon fiber manufacturers, accumulating valuable process data and application experience      in the preparation of T700 and T800 grade carbon fibers.
