A specimen in dia.=3
x L=10 mm with thermocouple dia.=0.2R
welded on one side is inserted into a quartz
tube and a quartz rod is set as shown in the
drawing. The specimen is heated in radio
frequency induction coils and cooled by
cooling media sprayed through nozzles on
inner coil by grasping thermal dilation by
differential transformer during the process,
transformation of metallic structure of iron
and steel and also thermal treatment
characteristics can be measured / recorded.
Temperatures, dilation quantity and time
data memorized in the data logger are read
out and automatically operated / analyzed =
transformation temperature detected so that
CCT / TTT curves are obtained.
