The ability of
Lepel's induction heating process
to provide heat exactly where it
is needed, for the exact amount
of time necessary for optimum quality,
makes it ideal for a variety of
precision heat treating applications.
The chance for distortion, warpage
and decarburization that can occur
with other heating techniques is
greatly reduced with induction heating.
Annealing
Providing exceptional accuracy and
control, induction heating is perfect
for annealing cold work materials.
Parts can be annealed with or without
a controlled atmosphere, and can
even be annealed right on the production
line. Localized annealing can be
accomplished with special coils.
Wire and tube annealing can be easily
done in an inert (argon, nitrogen)
or reducing atmosphere (nitrogen-hydrogen
or pure hydrogen) by using specially
designed chambers. Cooling can be
done in the same type of atmosphere.
Tempering
The rapid heating and controlled
temperatures of induction heating
produce the same hardness as traditional
tempering, but in much less time.
Other
Heat Treating Applications
Normalizing and stress relieving.
The localized heat used in induction
heating is ideal for relieving stress
caused by welding, hardening or
brazing to restore ductility and
prevent cracking. Use of induction
for preheating before welding can
minimize such stresses.
Hardening. Induction heating
effectively hardens the outer layer
of a part to a specified depth while
retaining the rest of the part's
original ductility. The depth of
hardness can be precisely controlled
with various methods like changing
power density, frequency and part
feeding rate. Shafts, tubes, gears,
etc., can be hardened without the
need for finishing after quenching.
A wide variety of Lepel power supplies
enable our application engineers
to select the optimum concept for
through hardening, case hardening,
contour hardening, single shot hardening
and scan hardening.
