Abstract

PURPOSE: To shorten largely vacuum exhaust time after assembly, by carrying out vacuum heating process in advance before machining and assembly for members to be used for vacuum structure.
CONSTITUTION: Gas exhaust process is carried out through the vacuum under heating in advance before machining and assembly for members to be used for vacuum structure. That is, steel member in state of blank is cut preferably in size, flat plate before machining cylindrically is placed in the vacuum heating furnace, carring out vacuum heating gas exhaust process, machining required shape, assembling as a product, carrying out vacuum exhaust to make a vacuum structure. Therefore, large amount of materials can be treated at a time, vacuum exhaust time after assembly is reduced largely.
