    • This invention provides a method for infusibilization of pitch fibers for production of carbon fibers which comprises putting pitch fibers prepared by melt spinning from a spinning pitch in containers, introducing in succession the containers containing the pitch fibers into an infusibilizing furnace divided into a plurality of sections and passing the containers therethrough from inlet to outlet wherein the containers containing the pitch fibers are intermittently moved through the infusiblizing furnace to retain each of the containers in respective sections for a given period of time, during which temperature of respective sections is independently raised from minimum controlled temperature to maximum controlled temperature and thereafter is lowered to the minimum controlled temperature and then the container is moved.
    • 本发明提供了用于生产碳纤维的沥青纤维不熔化的方法,其包括将通过熔融纺丝制备的沥青纤维从纺丝沥青混合在容器中,将含有沥青纤维的容器连续引入分为多个部分的熔化炉 并且使容器从入口到出口通过,其中容纳沥青纤维的容器被间歇地移动通过熔化炉,以将每个容器保持在相应的部分中一段给定的时间段,在此期间各部分的温度独立地从最小 控制温度到最大控制温度,然后降低到最低控制温度,然后移动容器。
