40MN双动铜挤压机挤压筒冷却效应研究

摘要

通过对具有螺旋线型冷却槽的挤压筒结构应力和热应力计算及冷却效应的对比分析，给出了对实际设计、工艺过程有重要意义的初步结论。%The structural and thermal stress distribution of the containerwith spiral cooling groove is calculated using direct coupled-field analysis of FEA.The cooling and nocooling effects and the preliminary result of the analysis are discussed here.
