Abstract:

To meet the requirements of high precision of temperature control, high heating rate, accurate measurement of gas flow rate and drafting rate of the carbon fiber, a distributed computer control system was designed for a new type fluidized preoxidation furnace test line. According to the requirement of the carbon fiber production process, the performance of the furnace was tested. The results showed that all the performances, such as temperature control, gas flow rate, and heating rate could meet the requirements.

Key words: carbon fiber, fluidized pre-oxidation furnace, computer controlling, performance testing
