摘要
应用ANSYS软件对真空练泥机挤出过程中陶瓷泥料的温度场进行分析,通过对在不同摩擦系数、不同外界温度、给泥料加热到不同温度等热参数下的运动泥料进行数值模拟,得出了泥料在热参数的影响下螺旋槽内的温度变化规律。结果表明泥料在挤出过程中由于温度的变化引起速度和压力变化,从而影响泥料在挤出过程中的流动质量,为陶瓷用真空练泥机泥料挤出生产的研究提供了理论依据。
In this paper,the temperature field of the pug in the extrusion process of de-airing pug mill has been analyzed with ANSYS,and the temperature variation of the pug in spiral groove under the influence of different thermal parameters,such as friction coefficients,outside temperatures and heating temperatures,has been obtained through numerical simulation.The results show that changes in pug velocity lead to temperature and pressure changing in the extrusion process,and in turn affect the pug＇s flow quality.The study can,therefore,provide theoretical basis for the research on extrusion production of the ceramic pug.
