See full text

A brazing furnace (1) includes a preheating chamber (2) and a brazing chamber (3). The preheating chamber (2) includes: a vacuum pump (21) for reducing the pressure inside the preheating chamber (2) while a material to be processed (100) is housed therein; a preheating apparatus (22), which preheats the material to be processed (100) in a reduced-pressure atmosphere; and a gas introducing apparatus (23), which introduces inert gas into the preheating chamber (2) to restore the pressure inside the preheating chamber (2) after the preheating. The brazing chamber (3) includes: a gas-replacing apparatus (31), which introduces inert gas into the brazing chamber (3); and a main heating apparatus (32), which heats the material to be processed (100) to a brazing temperature while it is housed in the brazing chamber (3).
