The invention relates to the technical field of quartz glass production, and discloses a quartz glass ingot isometric control method which comprises the following steps: igniting a combustor and releasing heat to enable the temperature in a hearth to reach a preset temperature, meanwhile, promoting a rotating shaft to rotate so as to drive a bearing plate arranged at the upper end of the rotatingshaft to circumferentially rotate, introducing a silicon-containing raw material into the combustor so as to enable the silicon-containing raw material to be molten or chemically reacted in flame of the combustor to generate silicon dioxide particles depositing on the bearing plate to form a quartz glass ingot, driving the bearing plate to move downwards in the vertical direction by the rotating shaft, and after the deposition height of the quartz glass ingot in the vertical direction reaches the preset height, extending a forming mold into a hearth from the side wall of the hearth and makingcontact with the peripheral side face of the quartz glass ingot. The quartz glass ingot isometric control method has the advantages that the isometric degree of the quartz glass ingot can be guaranteed and a folding layer is prevented from being generated in the deposition process of the quartz glass ingot.
Description
technical field [0001] The invention relates to the technical field of quartz glass production, in particular to a method for controlling the isodiameter of a quartz glass anchor. Background technique [0002] The deposition of the existing quartz glass anchor is first to melt the quartz sand or silicon-containing compound through the burner. After the quartz sand or the silicon-containing compound passes through the burner, it will melt or chemically react to form silica particles, and finally deposit layer by layer on the surrounding surface. any contact with the deposition substrate. During the long-term deposition process of quartz glass, due to the influence of temperature fluctuations or unsteady return of the car, the quartz glass anchor is under the action of centrifugal force generated by high temperature and rotation, which can easily lead to a "cucurbit-like" appearance of the deposited quartz glass anchor. , That is, the formed quartz glass has a poor anchor iso...
