The invention relates to the technical field of optical fiber manufacturing, and discloses optical fiber preform wire drawing equipment for optical fiber manufacturing, the optical fiber preform wire drawing equipment comprises a furnace body and a controller, a heat control assembly is arranged in the furnace body, the heat control assembly is electrically connected with the controller, a graphite piece located on the inner periphery of the heat control assembly is arranged in an inner cavity of the furnace body, and the graphite piece is electrically connected with the controller. An optical fiber preform is placed in the graphite piece, and a gas storage box is arranged at the upper end of the graphite piece. The gas storage box is arranged at the top end of the graphite piece, and the temperature of protective gas to be introduced into the graphite piece is adjusted through the gas distribution cavities distributed in the gas storage box in the radial direction and the axial direction and the preheating temperature detectors and the inner heating coils located in the gas distribution cavities. Therefore, the protective gas entering the graphite piece can utilize the heat carried by the protective gas to compensate the temperature in the graphite piece, the temperature difference in the transverse position in the inner cavity of the graphite piece is reduced, gas flow caused by large temperature difference is avoided, and the uniformity of the temperature in the graphite piece is improved.
Description
technical field [0001] The invention relates to the technical field of optical fiber manufacturing, in particular to an optical fiber preform drawing equipment for optical fiber manufacturing. Background technique [0002] Optical fiber drawing is the operation of drawing the manufactured preform into an optical fiber, that is, reducing the diameter of the optical fiber preform, and maintaining the core cladding and refractive index distribution is inconvenient. In the process of optical fiber drawing, the temperature distribution in the furnace is the key factor affecting the quality of the optical fiber, and the temperature and velocity distribution of the gas inside the drawing furnace are important factors affecting the temperature distribution in the furnace. This is because the fluctuation of the air flow will lead to the fluctuation of the temperature in the furnace, which will cause the uneven heating of the preform, which will lead to the fluctuation of the fiber di...
