Abstract

The invention discloses a method for producing a spheroidal quartz glass rod. The method comprises the following steps of: partially heating a part needing heating at the middle part of a quartz rod serving as a raw material on a thermal processing machine tool; extruding the two ends of the quartz rod serving as the raw material; extruding a rough rod with convex ball; and grinding the rough rodwith convex ball on a profile modeling machine tool into a finished rod. The method has the advantages of saving the consumption of the raw material in the conventional process, reducing the machining amount during the machining and preventing the crack damage caused by the machining, along with accurate size of the machining and extremely high production efficiency.

Description

technical field [0001] The invention relates to a production process of a quartz glass rod, in particular to a production method of a spherical quartz glass rod. Background technique [0002] Quartz glass is widely used in optical fiber communication, microelectronics, electronic semiconductor, solar energy, aerospace, laser and new light source and other technical fields. With the rapid development of the optical communication industry, the optical fiber manufacturing industry also develops rapidly. The two most representative processes for optical fiber production are: the emerging VAD process and the traditional MCVD process. The VAD optical fiber manufacturing process originated in Japan. It was successfully researched in 1996. Since its inception, it has impacted the traditional MCVD manufacturing process at an inestimable speed. The quartz glass holding rod is a consumable material used in conjunction with the VAD process. Various optical fiber manufacturing companies...
