摘　　要：柔性玻璃在成型阶段所使用的溢流下拉法和狭缝下拉法工艺繁琐,且难以准确预测不同工艺参数的影响。针对以上问题,设计了一种采用双溢流槽内侧双斜坡狭缝结构,使得玻璃液汇合于楔形板尖部的新型下拉法,用以生产玻璃厚度可实时调节的超薄玻璃。使用计算流体力学软件Fluent对成型过程进行数值模拟,分析了溢流槽上、下倾角的不同组合对溢流槽出口台阶上玻璃液分布情况的影响。The overflow and slit pull-down processes used by the flexible glass in the forming stage are complicated,and it is difficult to accurately predict the impact of different process parameters.For the above problems,a new pull-down method using the double slope slit fused to the wedge plate tip was designed to produce ultra-thin glass with a wide plate surface whose thickness can be adjusted in real time.Subsequently,a numerical simulation of the molding process was conducted using the computational hydrodynamic software Fluent to analyze the effect of the upper and lower inclination angles of the overflow groove on the distribution of glass fluid on the steps of the overflow tank outlet.
