Rolls and Shafts
Flame-hardening is the best,
and sometimes the only, way to heat-treat large
and outsized rolls. Less distortion and higher surface
hardness, combined with ductility and core strength,
are the results of flame-hardening.
Our process is also capable
of selectively hardening varying diameters on the
roll body, bearing fits, along with

the journals when required.
Flame-hardening of rolls provides
a better wear surface, uniform case, maximum hardness,
while leaving a both a tough and ductile core.
Gears
and Sprockets
Gears, sprockets and gear
racks benefit the most from quality flame-hardening.
Replacement of worn gears can be expensive, time
consuming and difficult. Chicago Flame’s techniques
give you maximum durability for longer wear.
We can harden gears of any
size,

whether cast or fabricated. Only the contact surfaces
of the teeth are treated, leaving the base metal
at its original strength.
Liners,
Machine Ways, and Rails
Flame-hardening is the best
and quite often the only process for selective hardening
of large or unusual shaped liners, ways and rails.
Chicago Flame Hardening has a unique process on
this application.

parameters for straightening tolerances and grind
