摘　　要：建立了浮法工艺玻璃成形过程的玻璃带三维(3D)与Thin-Film模型,采用Ansys Polyflow软件对600 t/d锡槽内玻璃带成形过程进行了模拟研究,与3D模拟结果对比表明,Thin-Film模型可准确、高效地模拟玻璃带成形过程。根据玻璃带成形过程模拟结果,讨论了锡槽不同区域内玻璃带的成形状态,进一步模拟分析了玻璃带纵向与横向温度分布条件对不同厚度玻璃成形过程的影响,得到了4mm与10 mm浮法玻璃成形过程的较优成形温度条件。A three dimensional(3 D)model and a thin-film model were proposed for the glass ribbon forming process in float process.The forming process of glass ribbon in a 600 t/d tin bath was simulated via a software named Ansys Polyflow.Compared to the 3 D model,the thin-film model is demonstrated to be more accurate and effective for the simulation of glass ribbon forming process.According to the simulation results,the forming process of glass ribbon in each zone of the tin bath was discussed.The influences of longitudinal and transverse temperature distributions on the forming process were analyzed for glass ribbons with different thicknesses.Finally,the optimized forming temperature condition is obtained for glass ribbon with a thickness of 4 mm or 10 mm,respectively.
