摘　　要：为了改变玻璃管水平拉制成型以直觉知识为理论基础和经验设计为技术手段的现状,本文采用ANSYS Polyflow软件建立了玻璃管水平拉制成型过程中的传热和传质数值仿真模型,得到了温度场、速度场、压强场、黏度场等的变化情况。通过数值仿真分析,得出玻璃液流入温度、牵引速度、鼓入空气流入压强和旋转筒转速都是影响玻璃管成型的敏感工艺参数。玻璃液流入温度和鼓入空气流入压强与玻璃管外径成正比,与玻璃管壁厚成反比;牵引速度与玻璃管外径和壁厚都成反比;旋转筒转速与成型位置的偏心量成正比。本文提出的数值仿真模型将为提高玻璃管品质,缩短换品调整时间,提高生产效率,节约材料和能源消耗提供理论支撑。In order to change the present situation of horizontal drawing forming of glass tube based on intuitive knowledge and empirical design,a numerical simulation model of heat and mass transfer in horizontal drawing process of glass tube was established by using ANSYS Polyflow software,then the changes of temperature field,velocity field,pressure field,viscosity field and so on were obtained.Through the numerical simulation analysis,it is concluded that the molten glass inflow temperature,pulling speed,blowing air inflow pressure and rotating cylinder rotational speed are all the sensitive technological parameters affecting the glass tube forming.The molten glass inflow temperature and blowing air inflow pressure are directly proportional to the outside diameter of glass tube and inversely proportional to the wall thickness of glass tube.The pulling speed is inversely proportional to both the outer diameter and the wall thickness of glass tube,and the rotating cylinder rotational speed is directly proportional to the eccentricity of the forming position.The numerical simulation model proposed in this paper will provide theoretical support for improving the quality of glass tube,shortening the replacement adjustment time,improving production efficiency,and saving material and energy consumption.
