Self-shaping method for gas-smelted quartz glass ingots

Abstract

The invention relates to a self-shaping method for gas-smelted quartz glass ingots. The self-shaping method comprises the following steps: adding a silicon material into a quartz beating machine, melting and flowing into a furnace chamber of a smelting furnace under the action of high temperature oxyhydrogen flame, carrying out deposition heap-up dissolving operation, forming concentric circle molten glassy-state cylindrical quartz glass ingots with different diameters at different deposition heights in a deposition growth and flowing process; and when the height of the ingots is stacked and grows to every 20 mm-50 mm, beginning to self-shape, allowing a quartz flame head and the molten glassy-state cylindrical quartz glass ingots together to move to the inner wall of the furnace chamber of the smelting furnace in a radial movement manner, making the maximum diameter of the molten glassy-state cylindrical quartz glass ingots produce friction with the inner wall of the furnace chamber,producing deformation, and making the product external dimension meet upper-and-lower equal diameter requirements in the height range, so as to obtain the product. The friction force between objects is used for shaping the appearance size of the product, the shape of the quartz glass ingots can be precisely controlled, the appearance defects of the product can be reduced, the efficiency can be improved and the production cost can be reduced.
