Abstract

The invention relates to a method and a device for drawing quartz glass fibers by using a quartz glass thick rod, and belongs to the technical field of quartz glass fiber production. An internal mixing combustor a and an internal mixing combustor b are used for conducting wire drawing operation on a quartz glass rod in a two-stage melting mode, the problems that existing quartz glass bars are frequently replaced, large-diameter quartz glass bars are modified, and consequently the wire drawing and twisting production efficiency is low are effectively solved. The method can improve the production efficiency effectively, the quartz glass rod does not need to be frequently replaced in the production process, and the large-diameter quartz glass rod remanufacturing and wire drawing operations are integrated, so that the method has positive significance on enterprise benefits.

Description

technical field [0001] The invention relates to a method and a device for drawing quartz glass fiber by using a quartz glass thick rod, belonging to the technical field of quartz glass fiber production. Background technique [0002] At present, the manufacturing method of quartz glass fiber is mainly through the first-level wire drawing method. Although this method can be used for stable wire drawing, due to equipment and process reasons, the diameter of the used quartz glass rod must be 2-3mm. The diameter of the glass rod determines the flexibility of the quartz glass rod, that is, the smaller the diameter and the longer the quartz glass rod is, the easier it is to bend during the wire drawing process. Therefore, the diameter of the existing quartz glass rod limits the flexibility of the rod. Length, in order to ensure that the quartz glass rod does not bend, the length of the quartz glass rod with a diameter of 2-3mm is generally 1.5-1.8m. Since the existing quartz glass ...
