Abstract
The invention discloses a large D-shaped Nb 3 Sn superconducting coil heat treatment equipment, including D-shaped furnace shell, insulation layer, D-shaped heating chamber, D-shaped ring cavity uniform temperature radiation screen, protective gas circulation diversion system and gas pipeline, etc. This heat treatment equipment is a special heat treatment equipment designed for D-shaped superconducting coils, and can be used for heat treatment of other D-shaped workpieces. The design of the protective gas circulation diversion system can improve the heat treatment temperature uniformity of the superconducting coil to ±3°C on the one hand, and ensure the cleanliness of the superconducting coil on the other hand. The invention has the advantage that the heat treatment equipment adopts the idea of redundant design, which improves the safety and reliability of the heat treatment of the superconducting coil. Adopting the heat treatment method of the protective gas circulation guide can improve the uniformity of the heat treatment temperature of the superconducting coil, and can also reduce the construction cost of the equipment. This system is suitable for heat treatment of large D-shaped superconducting coils with a length of 22m and a width of 15m, meeting the requirements of large D-shaped Nb 3 Sn superconducting coil heat treatment technical requirements, improve Nb 3 Superconducting properties of Sn superconducting coils.
Description
technical field [0001] The present invention relates to D-shaped Nb 3 Sn superconducting coil heat treatment technical field, especially a large D-shaped Nb 3 Sn superconducting coil protective atmosphere heat treatment furnace system. Background technique [0002] Energy shortage and environmental pollution caused by the use of traditional fossil energy are two key issues in the development of countries around the world today. Compared with fission nuclear energy, fusion energy resources are more abundant, with high mass-energy density, no high-level radioactive waste discharge, and environmental friendliness. It is an ideal new energy source in the future, and it is also the most likely feasible way to solve human long-term energy problems. one. At present, the scientific research on fusion energy in the world mainly includes magnetic confinement fusion and inertial confinement fusion. The scientific feasibility of magnetic confinement fusion energy has been verified on...
