Problems solved by technology

[0003] The purpose of the present invention is to provide a method to overcome the disadvantages of the existing gas smelting furnaces that can only produce a single ingot intermittently, and cannot manufacture ingots with non-circular cross-sections; by setting a melting pool and a forming port in the melting furnace, the raw materials are melted in the melting pool Then pull out the ingot through the forming port; it can not only manufacture circular or non-circular cross-section ingots, but also realize continuous production of gas refining and continuous melting of transparent quartz glass ingots.

Abstract

The present invention is continuous transparent quartz glass ingot melting apparatus and process, and belongs to the field of quartz glass melting technology. The melting apparatus consists of one hydrogen burner, one smelting furnace with one melting bath and one forming port, one ring smoke flue, one furnace seat and one drawing machine. The continuous melting process includes the steps of setup, preheating, feeding material, drawing ingot and cutting ingot. The present invention can produce ingot of circular or non-circular cross section, and has high heat efficiency and high quartz glass ingot quality.

Description

Technical field: [0001] The invention relates to a melting equipment and a melting process for continuous melting of a transparent quartz glass ingot by gas smelting, belonging to the technical field of quartz glass melting. Background technique: [0002] The currently used gas refining method for melting transparent quartz glass ingots is to use a hydrogen-oxygen burner to heat the bottom ingot in a furnace with an open bottom and feed materials to it, so that the raw materials are deposited on the bottom ingot, and at the same time, the bottom ingot is lowered to form a cylinder Shaped ingot (see accompanying drawing 1). The internal quality, appearance and production cost of the molten ingot made by this melting method mainly depend on the structure of the melting furnace and the ingot machine, and the currently used melting furnace has the following disadvantages. 1. There are contradictory requirements for the inner quality and appearance quality of the molten ingot to...
