    摘要:

    提出在中試水平的空心銅管坯水平連鑄過程中施加工頻電磁場(chǎng),分析其對(duì)銅管坯組織和性能的影響.結(jié)果表明：與未施加電磁場(chǎng)時(shí)相比,施加電流強(qiáng)度為140A的工頻電磁場(chǎng)后,水平連鑄空心銅管坯的組織顯著細(xì)化,平均晶粒度由未施加磁場(chǎng)時(shí)的3.1提高到8.3,周向組織均勻性也得到明顯改善;抗拉強(qiáng)度提高40%左右,延伸率提高50%左右.

    Abstract:

    In order to improve the quality of hollow Cu tubes, a horizontal continuous casting technology was developed in a pilot scale by using electromagnetic field of commercial frequency, and the effect of electromagnetic field on structure and mechanical properties were studied. The results show that the structure of hollow Cu tubes is refined substantially with the application of electromagnetic field and the average grain grand is increased from 3.1 to 8.3 and the uniformity along the circumference of the structure is improved obviously at the same time. The tensile strength is increased by 40% and the elongation is improved by 50% averagely if compared to those without electromagnetic field.
