Delubing of parts is achieved using our
Moisture Control System
This
system is the result of years of successful testing
and has been in actual production sintering on continuous
belt furnaces in our customers' plants since 1997. The
concept of this system is unique to any other system
offered in the market today. This technology will keep
a continuous, preset dew point in the preheat zone of
your furnace during processing. Also, there are no combustible
gases or high operating or maintenance costs to contend
with.
The
system operates using small amounts of N2 and H2O with
the capability of varying each component to fit your
operation. The addition of an oxidant (H2O) to the preheat
zone prohibits excessive lubricant deposits by combining
with the carbon from the lubricant to form the gaseous
products CO and CO2.
The
reduction of these high carbon vapors, to the gaseous
state, will result in more efficient lubricant removal
from the part surface, as well as from the furnace components.
It will reduce soot buildup and help reduce part blistering,
as well as eliminate carbide formations that collect
on the furnace components and reduce stack emissions.
Our recently improved, maintenance-free panel features
a digital temperature read-out, high and low temperature
safety shut-off with alarm, and a metered water pump
which eliminates the occasional inconsistency in the
previous water flow meter. Customers who purchased our
early models can easily retrofit any of these advancements
to their old systems, if desired. The Moisture Control
System is also applicable to Brazing
and Annealing processes.

Panel
— The moisture control panel is supplied
as shown and should be mounted as close as possible
to the point of injection.

|
Furnace
- Exit end — This shows the exit end
of the same furnace. Note there are no soot deposits
in this area. This is a strong indication that
soot is being removed before it can be dragged
by the belt, through the entire furnace. If soot
enters the higher temperature zones it will have
a negative effect on the furnace components whether
they are muffle or brick
|
 |
Furnace - Entrance end — This shows
a furnace operating with the "Moisture Control
System". This furnace has been in production
for over 5 years sintering iron-carbon, as well
as copper infiltrated parts and has never been subjected
to air for "burnout"
