两种铜母线热挤压模的使用情况探讨

Discussion on Two Kinds of Hot Extrusion Die for Copper Bus-bar

本文介绍了3Cr2W8V合金钢模和金属陶瓷模的主要特点,分析了这两种挤压模在铜母线热挤压生产中的使用性能。实践表明,在铜母线热挤压生产中,金属陶瓷模在许多方面优于3Cr2W8V合金钢模。

The paper introduces the main characteristics of 3Cr2W8V alloy steel die and cermet die,analyzes their operational performances in the hot extrusion production of copper bus-bar.The production practice shows that cermet die is superior to 3Cr2W8V alloy steel die in many aspects.
