In a steel mill?    These were big 3- or 4-foot long Pt/Pt+10% Rh
thermocouples.  The wire was threaded through ceramic beats, then placed
inside of a ceramic tube, then placed in a larger grey-black outer tube
(SiC, maybe?).  Used for temperature control in soaking-pit furnaces in the
blooming mill.  That particular summer taught me how much dry heat a human
could take in short doses--the next year, a co-worker collapsed and died
while changing a thermocouple.

Anyway, the thermocouples got bumped during loading and unloading the
furnaces and were broken pretty often.  When repairing a thermocouple, on
of the goals was to butt-weld any wire pieces together. A job that I
couldn't do.

Cheers,
Chuck
