摘要
重力支撑(GS)作为国际热核聚变实验堆(ITER)磁体支撑系统的关键部件,不但要承受环向场超导磁体净重以及交变的电磁载荷,同时还需隔离来自杜瓦环的热量以维持环向场超导线圈的热稳定性。为确保ITER超导磁体重力支撑高温合金螺栓能够安全服役于77K 12万次、4Hz、3200kN±400kN的循环往复载荷之下,本文基于ITER超导磁体重力支撑的极端工况阐述了718合金的生产工艺及质量控制要点。
Gravity support(GS), as a key component of the magnet support system of the International Thermonuclear Experimental Reactor(ITER), not only has to withstand the net weight of the toroidal field superconducting magnet and the alternating electromagnetic load, but also needs to isolate the heat from the Dewar ring in order to maintain the thermal stability of the toroidal field superconducting coil. In order to ensure that the ITER superconducting magnet gravity support super-alloy bolt can be safely served under 77K 120,000 times, 4 Hz, 3200 kN±400 kN cyclic reciprocating load, the production process and quality control key points of 718 alloy based on the extreme working conditions of the ITER superconducting magnet gravity support have been described in the text.
