Preparation method, device and system for quartz ingots

Abstract

The invention discloses a preparation method, device and system for quartz ingots. According to the method, quartz particles are used for depositing the quartz ingots in a fusion way; the blanking speed is controlled according to the following steps that: when the deposited quartz ingot height is smaller than the critical height of the cross section dimension change, the deformation caused by quartz ingot cross section dimension deviation caused by self weight is compensated according to the principle that the blanking speed is lower when the height is smaller; the blanking speed is controlled; when the deposited quartz ingot height is higher than the cross section dimension change critical height, the blanking speed is controlled according to the compensation quantity of the cross section dimension change critical height. The device comprises a rotary platform ascending and descending motor, a quartz raw material feeding quantity controller and a host computer. The system comprises a correction coefficient obtaining module, a blanking speed control module, a quartz ingot height detection module and a quartz ingot lower section cross section dimension detection module. The quartz ingots with the uniform dimension are obtained on the premise of not increasing deposition devices, not improving the raw material loss, and reducing the processing work procedures.

Description

technical field [0001] The invention belongs to the field of quartz material preparation, and more specifically relates to a method, device and system for preparing a quartz ingot. Background technique [0002] The quartz material used in the optical fiber preform has strict requirements on its appearance uniformity, bubble content, and impurity content. At present, the appearance uniformity of the quartz material prepared from high-purity quartz sand needs to be passed through subsequent multi-channel Process processing can meet the requirements. [0003] Gas smelting method is currently the main method for preparing quartz body materials using natural quartz sand as raw material. This method is to melt quartz sand under an oxygen-hydrogen flame to form quartz ingots with larger diameters. The obtained quartz ingots have different heights. The cross-sectional size deviation is large, which cannot meet the requirements of direct stretching. In order to solve the above prob...
