A self-shaping method for gas refining quartz glass anchorage

Abstract

The present invention is a self-shaping method for gas-refining quartz glass anchors. The steps are as follows: add silicon material into a quartz hammering machine, melt and flow into the furnace cavity of a furnace under the action of a high-temperature hydrogen-oxygen flame, and perform deposition and heap-dissolution operations. During the deposition growth flow process, concentric fused glass cylindrical quartz glass anchorages with different diameters are formed at different deposition heights; when the height grows to 20mm~50mm, self-shaping begins, and the quartz fire head and fused glass cylindrical quartz The glass anchors move radially towards the inner wall of the furnace cavity, so that the maximum diameter of the molten glass cylindrical quartz glass anchor will rub against the inner wall of the furnace cavity, resulting in deformation, so that the product's appearance size can reach the upper and lower diameters within the height range. requirements to obtain products. The appearance size of the product is adjusted by using the friction force between objects, so as to precisely control the appearance of the quartz glass anchor, reduce the appearance defects of the product, improve efficiency, and reduce production costs.
