摘　　要：利用反向凝固结晶器制造铜 /钢复合电车线 ,研究反向凝固条件下铸件的宏观组织及合金元素的分布 ,分析铜及铜合金的显微组织及硬度分布的规律。研究结果表明 :应用反向凝固技术 ,可以使铜包覆在钢芯上同时使合金元素分布于表面 ,进而在提高电车线强度的同时提高表面硬度。using reversing solidification crystallizing equipment to manufacture it, then the macrostructure of the samples and the distributions of alloy elements is studied, as well as the microstructure of copper and copper alloy and the distributing of hardness across the copper sample is analyzed. As the result, the copper can be packaged onto the steel core and the alloy elements can be distributed to the surface by using reversing solidification technology so that the strength and hardness of the electrical train wire is enhanced also.
