Embodiment Construction

[0023] Such as Figure 1 to Figure 2 As shown, a method of manufacturing a single piece of fireproof glass, the original piece of glass is selected for polishing, cleaned and dried, then heated in a high-temperature heating furnace 1, and finally cooled out of the furnace through a high-pressure air-cooling chamber 2, and the glass 3 is heated in a high-temperature heating furnace. 1 is driven by the roller 4 to perform reciprocating circular motion, so that the glass 3 is evenly heated. The high-temperature heating furnace 1 has two layers of heat radiation plates 5 and 6 evenly distributed on the upper and lower sides of the furnace body. The upper and lower ends of the upper heat radiation plate 5 are heated Electric heating bodies 7 and 8 are arranged under the radiating plate 6, and the heat radiating plate of each layer is formed by a plurality of small radiating plates 9 evenly distributed and arranged, and the heat radiating plates of the upper and lower layers are in t...

Abstract

The method is to do polishing, cleaning and drying for raw plate glass, then which is drawn out of furnace after cooling in high-pressure forced air cooling cell. There are two layers of heat radiant plate are set on top and bottom of high-temp. heating furnace uniformly, each of which consists of moutiple small radiant plate aranged in front, middle, rear three position corresponding relation uniformly. The heat radiant plate set in areas is exact controlled to ensure characteristic of glass uniform heating and process of cooling and heating to glass uniformly and performance parameter of fireproof glass by controlling air grides distance, wind pressure quantity and heating tem. according thickness of the glass when the glass is processed by wind cooling in forced air cooling cell. Refractory time of the fireproof is 89 minutes that is much more than standard time 60 minutes, quality of fireproof glass can be increased effectively by the invention.

Description

technical field [0001] The invention relates to a method for making a single piece of fireproof glass. Background technique [0002] The existing single-piece fire-resistant glass production method mainly uses materials such as ordinary flat glass or tempered glass as the original sheet, and on the basis of these semi-finished products, processes and methods such as polishing, cleaning, and fire-resistant treatment are carried out to meet the requirements of fire-resistant glass. performance requirements. The quality of its fire-resistant glass has reached the performance index of the national standard, mainly manifested in dimensional deviation, appearance quality, fire-resistant performance, curvature, light transmittance, etc. Fire-resistant performance should be one of the important properties of fire-resistant glass, and its fire-resistant treatment The main technological process is heating and cooling process control, which involves the situation of large area and thi...
