Description
Technical Field
The utility model particularly relates to a novel high-temperature-resistant waveguide tube.
Background
In the process of manufacturing an optical fiber preform by the PCVD process, a quartz liner tube is used as a substrate for manufacturing the preform and is placed in a high temperature furnace at 1000 ℃, and other gaseous raw materials are conveyed into the quartz liner tube through a pipeline, and are converted into plasma by means of microwave energy generated by a special device, so that sufficient chemical reactions can be performed to generate various components required for the optical fiber preform.
While high temperature resistant waveguides are required for microwave energy transmission to a liner tube located in a high temperature furnace at 1000 ℃, microwave transmission waveguide materials are generally optimized for the combination of brass and aluminum alloys (including economy), but brass suffers from a much reduced mechanical performance at 1000 ℃ and is susceptible to oxidation, while aluminum alloys cannot withstand the high temperature of 1000 ℃ at all. Therefore, when designing a waveguide used in such a high temperature environment, brass is used and an interlayer is designed in the waveguide wall, and cooling water is introduced to cool the waveguide.
