Abstract

The invention provides a production line of an ultra-low-expansion microcrystalline glass. The production line of the ultra-low-expansion microcrystalline glass mainly comprises a melting furnace, a forming machine, an annealing furnace, a crystallizing furnace, a conveying device and a rail, wherein the melting furnace, the forming machine, the annealing furnace and the crystallizing furnace are sequentially distributed on one side of the rail; and the conveying device is arranged on the rail and can move among the melting furnace, the forming machine, the annealing furnace and the crystallizing furnace. By adopting the production line of the ultra-low-expansion microcrystalline glass, provided by the invention, high-quality and large-scale microcrystalline glass products can be produced; and the products are specifically suitable for being used for meeting the demand of laser navigation equipment.

Description

technical field [0001] The invention belongs to the technical field of firing equipment. Specifically, the invention provides a continuous industrial production line for ultra-low expansion glass-ceramics. Manufacture of laser navigation devices. Background technique [0002] Ultra-low expansion glass-ceramic refers to Li 2 O, Al 2 o 3 and SiO 2 Glass as the main component is a transparent glass-ceramic with β-quartz solid solution as the main crystal phase formed after strict melting, homogenization, clarification, annealing and crystallization treatments. For ultra-low expansion glass-ceramics, the volume fraction of negatively expanding β-quartz solid solution in its unique chemical structure can be well matched with the volume fraction of positively expanding remaining glass liquid, so the thermal expansion coefficient of glass-ceramics can be controlled In a very small range, even glass-ceramics can achieve zero expansion within a certain temperature range. [000...
