中文摘要：

利用有限元分析软件ANSYS对螺旋绞刀流场进行分析，得到了泥料在双螺杆挤出机挤出过程的压力场、速度场和温度场。为泥料双螺杆机的研究提供了一定的理论依据，为提高泥料挤出效率和改善泥料挤出质量提供理论参考。

英文摘要：

The flow field of de-airing pug spiral reamer was analyzed by the FEM software ANSYS,the press field,velocity field and temperature field of ceramic paste extruding process in the twin-screw extruder were gained .It provides some theory reference for the research of ceramic paste twin-screw extruder, and it provides important guidance for improving extruding efficiency and quality of ceramic paste.
