CuCr触头材料的等离子熔炼工艺研究
摘要
分析了CuCr触头材料等离子熔炼工艺的特点
详细介绍了等离子炬的设计和熔炼实验系统。熔炼试验的初步研究结果表明

Abstract
The properties of arc melting techniques for CuCr contact materials are analysd. The design of plasma torch and the arc melting system are described in detail. Priliminary results obtained by this system show that
arc melting process will result in a fine grain size in comparison with conventional powder metallurgical process.
