Abstract

The invention discloses a quartz glass cast ingot production device, comprising a furnace body; a furnace cover is arranged on the top of the furnace body; a vent hole is formed in the furnace cover; inert gas is pumped into the furnace body through the vent hole; the furnace body is internally provided with a material carrying frame; the material carrying frame is used for providing a space for the production of quartz glass cast ingots; a heating device is arranged on the top of the material carrying frame; the material carrying frame is connected with a cooling device; the cooling device is used for cooling in the production process of the quartz glass cast ingots; the bottom of the furnace body is provided with a vacuum pump; the vacuum pump is used for extracting the air in the furnace body. Due to the structural design, the quartz glass cast ingot production device is capable of effectively removing bubbles in products, thus improving the density of the products and guaranteeing the product quality.

Description

technical field [0001] The invention relates to the field of glass ingot production equipment, and more specifically, to a quartz glass ingot production device. Background technique [0002] Quartz glass is a special industrial technical glass with a single component of silicon dioxide. It is mainly made of crystal, silica, and silicide as raw materials, and is formed by high-temperature melting or chemical vapor deposition. Quartz glass has very good light transmission performance, and has extremely high transmittance to ultraviolet, visible and infrared bands; quartz glass has good high temperature resistance and is a transparent refractory material. The use temperature is as high as 1100 ° C, which is higher than ordinary The temperature of glass is 700°C; in addition, the expansion coefficient of quartz glass is extremely low, which is equivalent to one-twentieth of ordinary glass, and its thermal stability is particularly good. Therefore, in high-tech fields such as ne...
