Abstract

The invention provides a high temperature-resistant high pressure-resistant glass observation window used for a vacuum furnace. The high temperature-resistant high pressure-resistant glass observationwindow comprises the following components by percentage: 75-88% of a glass substrate, 5 to 10% of a high-pressure reinforced substrate, 5 to 10% of a high-temperature reinforced substrate, and 2 to 8% of an adjuvant; the glass alloy substrate comprises the following components by mass percentage: 70-88% of fireproof glass and 12-30% of a molybdenum-based alloy; the high-pressure reinforced substrate comprises carbon fiber and ceramic fiber; the high-temperature reinforced substrate comprises flake graphite and alumina powder; and the adjuvant include a dispersant, a stabilizer, hydrogen peroxide, aluminum phosphate, an acidic aqueous solution of ethyl orthosilicate, and sodium silicate. The observation window has excellent fire resistance, high temperature resistance and high pressure resistance performance on the basis of ensuring a certain transparency, and is installed in an observation port of the vacuum furnace to effectively enable the operator to observe the situation in the furnace, and is helpful for the improvement of the processing efficiency.

Description

technical field [0001] The invention belongs to the field of vacuum furnaces, and in particular relates to a high-temperature and high-pressure resistant glass observation window for vacuum furnaces. Background technique [0002] Vacuum furnace is a kind of vacuum system (assembled by vacuum pump, vacuum measuring device, vacuum valve and other components) in the furnace cavity to discharge some substances in the furnace cavity, so that the pressure in the furnace cavity is less than a standard atmospheric pressure. The space thus realizes the vacuum state heating equipment. However, the current vacuum furnace cannot observe the specific heating conditions inside when it is working. It relies entirely on the parameters of the equipment outside the furnace, and the operating experience cannot be used accurately. [0003] Therefore, developing a high-temperature and pressure-resistant observation window for vacuum furnaces is an urgent problem for those skilled in the art to ...
