Description

本発明は、原子力発電用電圧レギュレータの溶接継目の加工の技術分野に属し、具体的には、球形ヘッドと筒体の内外面の溶接継目の加熱支持装置及び加熱装置に関する。 The present invention belongs to the technical field of processing a welded seam of a voltage regulator for nuclear power generation, and specifically relates to a heating support device and a heating device for a welded seam between the inner and outer surfaces of a spherical head and a cylindrical body.

原子力発電用電圧レギュレータの球形ヘッドを筒体セクションに溶接した後、溶接継目に加熱処理を行って、溶接応力を解消する必要がある。溶接継目の応力を解消する時には、所定の領域に対して、高温（６００℃）になるまで加熱する必要がある。従来行われている加熱の方式は、天然ガスを原料としてトーチで加熱することであり、これによって応力解消の効果を得る。 After welding the spherical head of a nuclear power voltage regulator to the cylindrical section, the weld seam must be heat treated to relieve welding stresses. To relieve stress in a welded seam, it is necessary to heat a predetermined region to a high temperature (600° C.). The conventional heating method is to use natural gas as a raw material and heat it with a torch, which has the effect of relieving stress.

従来技術では、トーチ加熱の方式を用いて、被加熱製品の異なる形状及び位置に対して加熱処理を行うことができるが、加熱の過程では、天然ガスが空気の中で燃焼し、筒体の溶接継目を加熱する時には、空気の流れ、環境温度などの要因の影響で、溶接継目に対する加熱効率は低く、加熱時間が延長し、エネルギーの無駄が多くなり、二酸化炭素、二酸化硫黄などの廃ガスが多く発生するため、現在の環境要件に合致しない。 In the conventional technology, the method of torch heating can be used to perform heat treatment on different shapes and positions of the heated product, but during the heating process, natural gas is burned in the air and the cylinder body is heated. When heating the welded seam, due to the influence of air flow, environmental temperature and other factors, the heating efficiency for the welded seam is low, the heating time is prolonged, there is a lot of energy wasted, and the waste gas such as carbon dioxide, sulfur dioxide, etc. This does not meet the current environmental requirements as it occurs frequently.

出願人は、上記の問題を解決するために、可撓性電熱シートを用いて溶接継目を加熱する方式を提案し、具体的には、可撓性電熱シートを被加熱領域に覆わせ、熱伝導の方式で熱を被加熱領域の表面に伝達することにより、製品に対する加熱処理を実現し、溶接継目の応力を解消する。前記加熱方式を用いる場合に、可撓性電熱シートを被加熱領域の表面によりよく貼り合わせ、固定して、加熱効率を一層高めるために、溶接継目の加熱支持装置を提案する。 In order to solve the above problem, the applicant proposed a method of heating the weld seam using a flexible electric heating sheet. Specifically, the applicant covered the area to be heated with the flexible electric heating sheet and By transferring heat to the surface of the heated area by conduction, heat treatment is achieved on the product and stress in the weld seam is relieved. When using the heating method, a heating support device for welded seams is proposed in order to better bond and fix the flexible electrothermal sheet to the surface of the heated area to further improve heating efficiency.

本発明は、従来技術の上記の欠点をなくすために、球形ヘッドと筒体の内外面の溶接継目の加熱支持装置を提供することを目的とし、当該装置は、可撓性電熱シートに対する固定及び押し付けを実現し、可撓性電熱シートを被加熱領域の表面に緊密に貼り合わせ、熱損失を避けて、加熱効率を高める。 In order to eliminate the above-mentioned drawbacks of the prior art, the present invention aims to provide a heating support device for the welded seam of the inner and outer surfaces of the spherical head and the cylinder body, which has the following advantages: Achieving pressing, the flexible electric heating sheet is closely attached to the surface of the heated area, avoiding heat loss and increasing heating efficiency.
