摘要:

为利于HL-2M真空室(VV)及极向场线圈(PFC)的整体安装,环向场线圈(TFC)采用比特板式结构,这种结构需要用到高强度高导电性能的大尺寸异形铜合金厚板以便满足线圈复杂受力的要求。通过应力分析,确定了在TFC上使用的3种铜合金。介绍了大尺寸异形铜合金板材的制造工艺和铜板多项性能的测试结果,结果表明异形铜合金板材的尺寸及各项性能均满足了HL-2M装置环向场线圈的工程设计及加工要求。

Abstract:

The demountable toroidal field coils (TFC) structure was adopted in order to assemble the vacuum vessel chamber and poloidal field coil (PFC) integrally in HL-2M tokamak. Copper alloy selection for TFC is a compromise between conflicting requirements for high fatigue strength and high electrical conductivity. After several stress analyses, three copper alloys were used in different parts of TFC. Adopting vacuum casting and forging manufacturing technology, large size and special shape copper alloy plates were fabricated. Under tests, the properties of copper alloy plate meet the requirements of TFC.

Key words: HL-2M tokamak, Toroidal coils, High stress, High electrical conductivity, Large size and special shape copper alloy plate
