Abstract

The invention relates to a glass rod material preparation method and a glass rod material preparation device. The glass rod material preparation method comprises the following steps: (a) putting a material into a material barrel; (b) feeding protection gas into the material barrel, a forming mold and a collimating mold; (c) controlling a heating unit to perform heating, preserving the heat till the temperature in the heating unit reaches softening temperature Ts of the material, controlling an annealing unit to be heated, and preserving the heat till the temperature in the annealing unit reaches annealing temperature of the material; (d) extruding the softened material, wherein after passing through the material barrel and being prepared into a rod material through the forming mold, the material enters the collimating mold; (e) enabling the heating unit to stop heating, naturally cooling the heating unit, preserving the heat of the annealing unit, and after the annealing unit is subjected to heat preservation for T, naturally cooling the annealing unit; and (f) after the annealing unit is cooled, taking out the material, and collimating and forming the material through the collimating mold, thus preparing the glass rod material. The forming mold is detachable, thus facilitating production of glass rod materials with different sizes; and furthermore, one forming mold can be provided with multiple through holes, so that the glass rod material production efficiency is improved.

Description

technical field [0001] The invention relates to a preparation method and a preparation device of a glass rod, in particular to a preparation method and a preparation device of a chalcogenide glass rod. Background technique [0002] Chalcogenide glass is a glass composed of sulfur (S) or selenium (Se) as the main component and other elements such as germanium (Ge), arsenic (As), antimony (Sb), etc. It has excellent optical properties in the infrared band . In recent years, the application of chalcogenide glass in infrared optics has become more and more extensive, and it is used in various civil and military infrared optics fields. Due to the high price of raw materials and complicated melting process, the price of chalcogenide glass is very high. In order to improve the melting efficiency and reduce the melting cost, chalcogenide glass is often melted into large-diameter glass ingots, but the actual chalcogenide glass lenses are usually relatively small in diameter. Proce...
