。Conventional vacuum brazing equipment uses a heating system consisting of a heater, an electrode arrow, an insulator, etc. inside a vacuum chamber, and a reflector that reflects the heat of the heater to provide heat insulation. Brazing is performed by heating the soldering material. For this reason, the surface area inside the tank is limited, the overall size of the apparatus is increased, and the heating system serves as a source of released gas, requiring a long time to evacuate the inside of the tank to a high vacuum.

年に１．２回行わなければならないため装置の稼動効率
が悪い。In addition, in conventional vacuum brazing equipment, in addition to insulating the tank with a reflector, the outer periphery of the tank is cooled with water, which creates relatively low-temperature parts inside the tank, such as electrode parts, tank inner walls, Various gases, oils, evaporated metals, etc. emitted from the objects to be brazed adhere to the rector adjacent to the inner wall of the tank, causing problems such as increased gas emitted during vacuum evacuation and deterioration of insulation. Therefore, it is necessary to periodically disassemble and clean the inside of the tank. This maintenance work will take about 3 weeks each time.
Since it has to be done once or twice a year, the operating efficiency of the equipment is poor.
本発明は上記問題に＆みてなされ、短時間で高真空に排

ウ材は装置によりて達成される。The purpose of the above is to heat the object to be brazed with the soldering material attached inside the vacuum chamber. A vacuum brazing material is achieved by the apparatus, which is characterized in that no heating means for brazing is provided, and the vacuum chamber itself is heated by a heating means provided outside.
真空槽自体を加熱するようＫしたことで、真空槽内部に
ヒータ、し７レクター、電極、碍子等を入れる必要はな
