Problems solved by technology

[0003] Among the existing melting furnaces for quartz products, such as the melting furnace disclosed in the patent publication number CN101148311B, the same as the existing melting furnaces, are suitable for the manufacture of quartz products. With the development of the market, the technology of quartz ingots is moving towards the direction of large size Development is imperative. Due to the need to produce large-sized quartz products, the size of the corresponding melting furnace needs to be increased accordingly. Especially in the preparation process of the furnace, the inner diameter of the zirconium corundum furnace is more than 700mm, and the total weight will exceed 500mm. Kilograms, in the process of sintering large-sized furnaces, it is easy to collapse, and the technical difficulty of manufacturing the furnaces is greatly increased, and the yield of the sintering process is very low, so there is a certain difficulty in the preparation of large-sized furnaces; at the same time, due to the long Time guarantees the high temperature in the furnace. The combustion nozzle of the hydrogen-oxygen burner in the existing melting furnace is prone to unstable combustion or even damage after working for a long time. However, due to the high temperature in the furnace, it is not suitable for the combustion nozzle. replacement, resulting in large economic losses

Description

technical field [0001] The invention relates to the technical field of melting furnaces, in particular to a large-diameter quartz ingot melting furnace. Background technique [0002] In recent years, the rapid development of my country's optical communication industry, semiconductor industry, solar photovoltaic industry and aerospace has provided a broader market for the development of my country's quartz glass industry. In the production of synthetic quartz glass, silicon tetrachloride and high-temperature water vapor formed by oxyhydrogen flame undergo hydrolysis reaction to form silica particles, and these fine particles are gradually deposited on the quartz substrate in the furnace. With the continuous supply of raw materials, the hydrolysis reaction continues, and the deposition of fine silica particles makes the deposition surface of the mound material thicker. Driven by the mound machine, the mound material gradually becomes larger and its length increases. [0003] A...
