电子管铜阳极废品分析

An Analysis on the Causes of the Waste Copper Anddes in Electron Tubes

对大功率电子管铜阳极半成品开裂进行了试验分析，结果表明，铸件内部存在着残余缩孔，在压力加工过程中造成产品开裂。

The cleavage of semifinished products of copper anodes used in the large power electron tube has been studied by experiments. Results show that,the cleavage is brought about in processing under pressure due to the remaining shrinkage cavities within the casts.
