摘　　要：中国聚变工程试验堆(CFETR)中心螺管模型线圈(CSMC)采用混合磁体结构,由超导Nb3Sn线圈和超导NbTi线圈相互同轴套装而成。由于Nb3Sn为脆性材料,将采用"先绕制后反应"的技术来完成超导Nb3Sn线圈的制造。热处理是超导Nb3Sn线圈制造的关键技术。中科院等离子体物理研究所针对CSMC线圈建立了一套大型超导线圈控制气氛热处理系统。利用该套系统完成了国内最大的Nb3Sn超导线圈热处理工作。热处理结果均满足超导线圈热处理技术要求。介绍了超导线圈热处理系统、工艺和实验结果。The China Fusion Engineering Test Reactor(CFETR)central solenoid model coil(CSMC)is composed of Nb3Sn and NbTi hybrid superconducting coils.As Nb3Sn is a brittle material,the technology of"wind and react"has been used to manufacture Nb3Sn coil.In order to complete the heat treatment of Nb3Sn coil,a heat treatment system was established in institute of Plasma Physics,Chinese Academy of Sciences(ASIPP).The heat treatment of the largest Nb3Sn superconducting coil in China was completed by using this system.The heat treatment results all meet the technical requirements.
