摘要
从光纤拉丝炉、光纤退火和光纤冷却等方面进行了分析,阐述了高速拉丝的工艺基础。从拉丝炉温场和气流场角度出发,探索了光棒直径与中心管直径的匹配范围;同时对光纤保温炉的温度和距离进行了摸索确定,可以有效提高光纤翘曲度,降低断纤率;光纤冷却用氦气流量在10 slm以上时,可以保证光纤内涂层的直径及光纤的微弯损耗。通过对上述参数的探索,确定了一套超高速拉丝的稳定工艺,实现了提速增效。
Abstract
This paper mainly analyzes the technology of high speed drawing from the aspects of fiber drawing furnace, fiber annealing, and fiber cooling. From the angle of the furnace temperature field and the airflow field, the distance between the diameter of the rod and the diameter of the center tube is explored. At the same time, the temperature and distance of the fiber holding furnace are explored and determined, which can effectively improve the optical fiber curl and reduce the broken rate. It is shown that the optical fiber cooling with He flow rate of 10 slm above can guarantee the diameter of the fiber coating and the microbend loss of the fiber. Through the exploration of the above parameters, we determine a set of ultra high speed drawing stable process, which can achieve a rapid increase in production and meet the market demand.
