Problems solved by technology

[0004] The main purpose of the present invention is to provide a chalcogenide glass air-cooling device and its air-cooling control method. The chalcogenide glass air-cooling device realizes that the synthesis container is stably and safely fixed in the center of the air-cooling chamber through a center positioning device and a fixing device. The setting of the guide mechanism realizes the uniform flow of the airflow to ensure the uniformity of the temperature of each part during the cooling process of the melt, so as to solve the technical problem that the cooling speed of the melt and the uniform air cooling cannot be controlled during the rapid cooling process in the prior art

Abstract

The invention provides an air-cooling device for chalcogenide glass and an air-cooling control method thereof. The air-cooling device for chalcogenide glass comprises a device body, a center positioning device, a synthesis container, a guiding mechanism and an air-cooling system. The device body includes an inner barrel and The outer barrel is sleeved on its outer side, and a closed and connected air-cooling cavity is formed between the outer side wall of the inner barrel and the inner side wall of the outer barrel; an air-cooling chamber is formed inside the inner barrel, and the air-cooling chamber and the air-cooling chamber are formed. The outer barrel is provided with an air inlet for connecting the air-cooling cavity; the air-cooling system communicates with the air-cooling cavity through the air-inlet; the center of the room. The chalcogenide glass air-cooling device realizes the stable and safe fixing of the synthesis container in the center of the air-cooling chamber through the center positioning device and the fixing device, and realizes the uniform flow of the air flow through the setting of the guiding mechanism to ensure the uniform temperature of each part during the cooling process of the melt. sex.

Description

technical field [0001] The invention relates to the technical field of chalcogenide glass preparation, in particular to an air cooling device for chalcogenide glass and an air cooling control method thereof. Background technique [0002] Chalcogenide glass is formed by introducing sulfur (S), selenium (Se), and tellurium (Te) of group VI in the periodic table and introducing other metal or non-metal elements (Ge, As, Sb, etc.) an amorphous material. Usually, a quenching medium is used to achieve rapid cooling of the melt to prepare amorphous chalcogenide glass. Commonly used quenching mediums are liquid (water, salt solution, oil, liquid gas), air, and liquid quenching medium has a cooling rate The advantages of fast and uniform quenching heat are often used in the preparation of amorphous materials with strong crystallization ability, but the liquid quenching medium cannot accurately ensure that the cooling rate remains consistent in the required temperature range. The ai...
