报道了铝挤压加工用铝方坯加热炉用高温超导磁体的研制和试验结果。在这种磁体中，高温超导线圈与铁芯结合在一起，因为工作区所需的磁场约为1T。制作了两个直接缠绕在凸形铁芯上的高温超导线圈。高温超导线圈是由无绝缘缠绕的REBCO带和Yoroi线圈技术制成的。它们中的每一个都单独安装在一个单独的低温恒温器中。两个带铁芯的高温超导线圈相对布置，并通过放置在室温下的C型线圈磁连接。在最初的冷却过程中，高温超导线圈被GM制冷机冷却到15K左右。在额定电流为200A的条件下，在加热区中心稳定产生1.06T的磁场，高温超导磁体在不失超的情况下可以充电到300A。通过从低温恒温器外部对电磁力方向的观察，证实了磁体力平衡设计的有效性。
This paper reported the fabrication and the test results of the high temperature superconducting (HTS) magnet developed for the aluminum billet heater for aluminum extrusion processing. In this magnet, the HTS coils were combined with iron cores, because the required magnetic field in the working region was about 1T. Two HTS coils wound directly on the convex shape iron cores were fabricated. The HTS coils were made by the no-insulation winding of REBCO tape with the YOROI-coil technique. Each of them was separately installed in an individual cryostat. Two HTS coils with iron cores were disposed oppositely to each other and were magnetically connected by a C-shape yoke placed in room temperature. The HTS coil was cooled down to about 15 K by the GM cryocooler in the initial cooling. The magnetic field of 1.06 T at the center of the heating region was stably generated with the rated current of 200 A. It was also demonstrated that the HTS magnet could be charged up to 300 A without quench. According to the observation of the electromagnetic force direction from the outside of the cryostat, it was confirmed the validity of the force balance design of the magnet.
