Continuous Pre-Oxidation Furnace

Purpose of the continuous preoxidation furnace

It is used for continuous pre-oxidation of materials based on PAN, on an asphalt-viscose basis, based on carbon fiber in a controlled oxygen environment.

Technical features of a tube furnace for continuous pre-oxidation 

  1. Special circulation of hot air and distribution of hot air, temperature uniformity ≤1.5 ℃ / m, air uniformity≤20%.
  2. Manufacturing technology for modular segments that can be flexibly combined to meet production requirements. 
  3. With the ability to perform in the form of a multilayer structure to reduce the room. 
  4. Automatic feeding and unloading of materials, easy to operate.

Accessories Options

  1. Continuous oxidation furnace tube: carbon steel / stainless steel 
  2. Furnace chamber design: single layer / multi-layer 
  3. Hot air circulation method: top and bottom / left and right / at the entrance from the rear end upper, turn from the entrance to the end side. 
  4. Hot air distribution: concentrate heating / uniform distribution / uniform heating / uniform distribution 
  5. HMI (interface) tube furnace for continuous pre-oxidation: analog screen / touch screen / industrial computer 
  6. PLC: OMRON / SIEMENS 
  7. Temperature Controller: SHIMADEN / EUROTHERM 
  8. Temperature Measurement: Thermocouple / Thermal Resistance 
  9. Electrical Elements: CHINT / SCHNEIDER / SIEMENS
