Description
Gas Nitriding Furnace For Aluminum Extrusion Die
Nitriding process divides into two kinds: one is gas nitriding
which used the ammonia gas for medium; the other is liquild
nitriding which used the nitrate liquid as medium, also called
"salt bath". But it is hard to buy the nitrade chemical and hard to
wash the die surface, so gas nitriding is more popular.
Vacuum varying pressure gas nitriding furnace also is
available.
The extrusion die works at the condition of strong extrusion
force and high temperature, it needs to stand the very strong
friction. So after the extrusion die used a certain time, it need
to use the nitriding furnace to do hardening process.
We are specialized in the production of gas nitriding for
hardening aluminum extrusion die, we have rich experience of
aluminum extrusion die treatment, we can supply the process
treatment guidance.
Application of gas nitriding furnace
This nitriding furnace is a series of batch-type pit-type
controlled nitriding furnaces and is used for nitriding metallic
tools and dies, camshafts, precision gears, etc. If this
nitriding furnace is equipped with a KRN-W or WPB-N series control
panel, the nitriding atmosphere, temperature, operating time, and
gas and liquid flow can be controlled automatically. This
series can also be used for various applications including
soft-nitriding, tempering, and stress relieving of steel parts, as
well as solution treatment of nonferrous metals.
Features of nitriding furnace
1. This nitriding furnace series is furnished with a KRN-W
nitrogen potential micro-processor. It measures, adjusts and
records the nitrogen potential, temperature, time, gas and water
flow automatically.
2. The unique doubly insulated furnace and circulating fan
mechanism allows nitrogen potential uniformity better than ±0.1%,
and internal pressure greater than **0 mm H2O.
3. The advanced ceramic tile lining greatly insulates the
furnace, significantly speeding heating and thereby saving up to
*0% in energy usage.
4. The rapid-cooling fan system shortens the production period
greatly.
5. If this nitriding furnace is equipped with a vacuum system,
it can be fitted for controlled pulse-nitriding.
We has exported this nitrding furnace to Egypt, Pakistan, Sri
Lanka, we have rich experience to supply after-sale
service.
