摘要
传统的接触式物理钢化炉对2 mm以下的超薄玻璃进行加热时无法保证玻璃表面的平整度,为此需要开发气悬浮式加热钢化方式。而加热过程中压力的均匀性是减少超薄玻璃在加热过程中发生形变的关键,为此必须设计合理的气悬浮式加热仓结构。文中采用Fluent软件研究了气悬浮式加热仓大小孔的不同排列方式、大小孔直径比例及小孔填充材料与玻璃表面压力分布的影响。并提出了一种评判压力均匀性的方法,给出了气悬浮式加热仓合适的结构参数。该研究工作对2 mm以下的超薄玻璃进行气悬浮非接触式加热可提供理论依据。
In view of the problem that the traditional heating tempering furnace can＇t guarantee the flatness when heated, Studying on a air suspension heating bin composed of big and small hole arranged in a certain way, analysis the influence of pressure distribution to glass surface of different arrangements of big , small holes and different filling materials of the small holes and . In order to provide theoretical basis for non-contact heating for ultra-thin glass under 2mm. Designing a reasonable structure which can make the surface pressure distribution more uniform, weaken the pressure peak. Focus on the analysis of the different pressure distribution of the arrangements, diameter ratio and the filing materials of the hole. The pressure distribution of different conditions are investigated using commercial software, Fluent. It can be found that the pressure distribution of the glass is more evenly after using the interval arrangement and the porous media. Compared with the traditional heating tempering thrnace, the air suspension heating bin can make sure the uhra-thin glass under 2ram relatively fiat while heating and reduce the deformation.
