L型挤出机头中物料温度分布的研究

对挤出机L型机头中流动物料的温度场分布进行了研究，提出了计算L型机头内物料温度分布的数学模型，并据此编制了CAE软件包。利用此软件包对两种不同的挤出物料进行了计算分析。通过分析计算结果，讨论了物料性能和机头温度对L型机头内物料温度分布的影响。;The temperature distribution of the flowing material in L-die of ext ruder was investig ated.A mathematical model for calculating the temperature distribution of the flowing material in L-die of extruder was established.Based on this，a CAE softw are package was worked out.A calculation analysis of two different materials was made with the software package.The results showed the effect of the properties of materials and the temperature of L-die on the temperature distribution of the flowing material in L-die
