The chalcogenide glass air cooling device comprises a device body, a center positioning device, a synthesis container, a guide mechanism and an air cooling system; the device body includes an inner barrel body and an outer barrel body arranged on the outer side of the inner barrel body in a sleeving manner, and a closed and communicating air cooling cavity is formed between the outer side wall of the inner barrel body and the inner side wall of the outer barrel body; an air cooling chamber is formed in the inner barrel body, and the air cooling cavity communicates with the air cooling chamber; an air inlet communicating with the air cooling cavity is formed in the outer barrel body; the air cooling system communicates with the air cooling cavity through the air inlet; and the synthesis container is vertically arranged in the center of the air cooling chamber through the center positioning device and a fixing device. According to the chalcogenide glass air cooling device, the synthesis container is stably and safely fixed to the center of the air cooling chamber through the center positioning device and the fixing device, and uniform flowing of airflow is achieved by installing the guide mechanism, so that the uniformity of the temperature of all parts in the melt cooling process is guaranteed.

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 based on sulfur (S), selenium (Se), and tellurium (Te) of group VI in the periodic table of elements, and is formed by introducing other metal or non-metal elements (Ge, As, Sb elements, etc.) an amorphous material. Quenching medium is usually used to achieve rapid cooling of the melt to prepare amorphous chalcogenide glass. Commonly used quenching mediums include liquid (water, salt solution, oil, liquid gas) and air. Liquid quenching medium has cooling speed The advantages of fast and uniform quenching are often used in the preparation process of amorphous materials with strong crystallization ability, but the liquid quenching medium cannot accurately ensure that the cooling rate remains consistent in the required te...
