Therefore, uniform airflow and temperature in the entire process room are key factors in producing high-quality pre-oxidized tows, and have always been the focus and difficulty of pre-oxidation furnace research.

Because the corner is fixed, the circulating wind cannot be flexibly distributed and adjusted, which makes it more difficult to control the wind direction in the furnace and adjust the wind speed uniformity, which in turn affects the quality of the carbon filament.
