Does anybody have any experience-based advice on prolonging the life
of an electric kiln? I.e., will a slow and gentle ramp-up, say, 500
F. per hour, to 1800 F. or 2000 F. make it-- the heating elements
and the refractory-- last longer than bringing it up to such temps
as quickly as possible?
I just got a small Paragon PMC kiln that I intend to use in
heat-treating alloy tool steel such as 440C stainless-- heating a
piece for 5 minutes or so at 1800 F. for the hardening phase and
then tempering 4 hours at 400 F. would be typical-- and want the
kiln to last as long as possible. Seems as if thermal shock would be
hard on it.
