吸収して薄帯の過熱を防止する。20 EB scanning uses an electromagnetic deflection coil to scan along a rectangle that is parallel to the strip width direction and has a length longer than the strip width on one side, and one EB device is used to scan in the strip threading direction. Tea
It is characterized by gradual heating in two zones: , and a2. Note that scanning in the threading direction is performed on the graphite 2, so that the graphite 2 absorbs EB in the threading direction to prevent overheating of the ribbon.
