Salt Bath Furnace
Although it may appear
that General Metal Heat Treating could have invested in other types of modern
furnaces with comparable prices and processes, we can offer you better quality
heat treating and increased versatility with our Upton molten salt bath line.
General Metal Heat
Treating's salt bath capability allows us to handle those really tough jobs
precision machined tool steel parts which are finished to size before
heat treating, but require hardening to as high as 65 Rc with minimum distortion
and dimensional change.
With our salt bath
line we are able to selectively or totally heat treat gears or elongated parts
up to 30" in length. Under special conditions, we are able to handle
parts up to 40".
Because salt baths
heat by conduction, rather than radiation, heat is applied more evenly and
quickly. Since the bath temperatures may be readily adapted to a higher or
lower temperature, General Metal is able to handle emergency jobs with minimum
interruption in the flow of our work.
Mechanical part handling
fixtures above the salt bath enable General Metal Heat Treating to treat a
large variety of parts . For selective hardening, parts can be suspended so
that only the portion to be hardened is immersed in the bath.
The Marquench, which
is adjacent to the salt baths, allows for immediate salt quenching. Quenching
is done in caustic, oil, austempering, or martempering salts at whatever temperature
is required. Our Gleason 25 Pressquench, which is also within close proximity,
has the capability of handling gears up to 24" in diameter.
