The present invention provides a winding frame suitable for manufacturing superconducting magnets by the (and React) method and a method for manufacturing the same.

た前述の欠点は解消する。 Conventionally, the following two methods have been used to manufacture superconducting magnets using compound superconducting wires such as Nb 3 Sn and V 3 Ga.
There are different types. The first method consists of a composite made by embedding a substance that produces a compound superconductor in a normal conducting substance, such as a composite of Cu-Sn alloy and Nb in the case of Nb 3 Sn. Lead wire (hereinafter referred to as “unreacted lead wire”)
This is a manufacturing method in which a superconducting compound is generated by heat-treating a superconducting wire (hereinafter abbreviated as . This method is similar to React and Wind.
It is called the Wind) method. However, compound superconducting wires are sensitive to stress and strain, and superconducting properties, especially critical current values, deteriorate due to tensile stress during winding and bending strain due to the curvature of the winding frame diameter. The disadvantage was that the specified performance as a superconducting magnet could not be obtained, and the current was reduced to a fraction of that. A manufacturing method proposed to eliminate the drawbacks of this react-and-wind method is the following wind-wind method.
This is the Wind and React method. That is, this is a method in which the unreacted conducting wire is wound around a winding frame and then subjected to heat treatment. According to this method, a compound superconductor is generated after winding an unreacted conducting wire around a winding frame, so the above-mentioned drawbacks of the React and Wind method are overcome.

される等の欠点があつた。 However, in the case of the Wind and React method, the entire insulation-coated winding frame and conducting wire are exposed to a heat treatment temperature of 550 to 850°C. Under such high temperatures, organic insulating materials such as formal and polyimide, which are commonly used for insulating superconducting wires and winding frames, are likely to decompose and lose their insulating function. Wind and
It is unsuitable for React method. On the other hand, methods of using high-temperature-resistant insulating materials include wrapping quartz glass tape, coating with polyvinyl acetate etc. and decomposing it at high temperature to form carbon, and coating with magnesium hydroxide and decomposing it at high temperature to form carbon. A method of forming a ceramic powder and a method of painting and baking ceramic enamel, which is a mixture of ceramic powder and enamel, are known. However, the quartz glass tape is too thick for the conductor dimensions, lowering the current density of the coil, and has weak strength, and carbon, magnesium oxide, and ceramic enamel tend to peel off easily. On the other hand, sodium oxide has good adhesion to copper alloys such as superconducting wires, and E-glass fibers can easily be used to insulate wires, making them suitable for covering superconducting wires. Not suitable for covering frames. In other words, sodium oxide has poor adhesion to the winding frame material such as stainless steel and easily peels off, and E-glass fibers require the introduction of superconducting wires or abnormal voltage detection lead wires at the ends (flanges) of the winding frame. It is difficult to completely cover parts with complex and minute shapes that have holes and cutouts for leading out, and it is not possible to provide sufficient insulation. Furthermore, there is a known method of coating such difficult-to-coat areas by adhering a powder mainly composed of oxide materials such as frit using a binder.
Because the adhesive strength is weak, peeling occurs when the temperature is lowered from the high temperature of 550 to 850°C, which is the generation temperature of compound superconductors, to the low temperature of 4.2K (-269°C), which is the operating temperature of superconducting magnets. There were drawbacks such as damage to the insulation and breakdown of the insulation.

There is a need for an insulating coating that has excellent insulation properties, is strong and wear-resistant, and does not peel off even under the above-mentioned large temperature changes. It is an object of the present invention to provide a winding frame for a superconducting magnet and a method for manufacturing the same that meets such demands.
