摘　　要： 离心式挤出机是一种新型挤出机,其固体输送段的加热冷却方式不同于传统单螺杆挤出机,而塑料是在热状态下加工的物料,温度控制对制品的质量影响很大。因此,必须对其固体输送段的传热部分加以研究,以确保生产顺利进行。主要采用有限元软件ANSYS传热分析模块来计算转鼓及其内部物料的温度分布情况,从而判断其加热冷却装置能否达到生产控温要求。 The centrifugal extruder was a new type equipment. The manner of heating and cooling of solid conveying was different from tradition single screw extruder. While plastic was processed when it was heated ,and temperature control affected products＇ quality. Thereby solid conveying part＇ s heat transfer must be researched to make sure produce quality. The temperature distribution of drum and materiel in it was mainly calculated, and the heating and cooling system according to demand of production control temperature was judged.
