we were donated a thermolyne 1400 furnace, it looks very handy but im curious if anyone happens to know exactly what the heating wire is that it
uses...

What type of furnace is it? If it's a 1400C tube furnace or muffle furnace then it probably uses a high performance nickel chromium element. Most
resistance elements are NiCr up until 1400-1500C where molybdenum disilicide, SiC, and graphite are the ones of choice.
Muffle furnace...

Its got a cool door that slides down, suppose to top out at 1200 C, Think i can replace the wire with a dryer heating element? lol, sad but im
serious...
The pyrometer works, and the refactory bricks seem intact, just the wire is broke in several places, (I think some freak boiled acid in it.)

Nichrome won't do much more than 1200C. If the length is right, sure.

Contact Thermolyne for a relacement heating element.
Anything else and you are asking for trouble.
Give them all the details from the ID plate on the furnace probably at rear. Serial number, model number, volta, amps, watts, everything.
I have withdrawn my earlier remark, as based on your reply I was mistaken..

ouch.

not quite like that, I had been talking to a machinist about his plans for a burnout oven... I was aware of its condition, saved me from making pretty
much the exact same box in the plans.. i was curious though if all items that use heating wire elements used the same thing, in which case i just
replace the wire and nothing else. as is, ill go through rebricking 1" with the plans wiring. I just never did anything refractory and wanted to save
as much time as possible.
I take out the trash as my job for the labs.. so either way, id have it. heh.
All the best peeps.

12AX7 : much thanks sir. I use the same gauge wire at same length and its gonna be close, baring anomolies with exact alloy, but one must be
realistic. many thanks.
