Machine
shops save time with a furnace at their disposal in their own shop. You
will no longer send a die out for heat treating, wait for its return
and then send it out again for additional heat treating.
Solid construction
The door swings open with one-handed
operation. The PMT-10 furnace is insulated with refractory firebrick.
The elements are mounted in dropped, recessed grooves machined into the
firebrick. Paragon invented this type of groove in 1952. This groove
protects the element for long life and low maintenance. Elements are
simple to replace because they’re exposed rather than embedded. You can
thread new elements into place following clear instructions in the
manual.
The firing chamber is protected by a steel
case painted in high temperature blue. A built-in stand lifts the
firing chamber safely off your worktable, so no extra stand is needed.
The door is mounted with a heavy-duty hinge for smooth opening. A
micro-switch shuts off the power to the elements when the door is
opened.
We use high temperature wire in the switch box for long life. A heat
shield, mounted between the switch box and furnace, helps keep the
switch box components cool even during extended operation. To further
dissipate heat, the switch box is extra large and generously louvered.
Each furnace comes with a cord and plug for immediate installation and
a one year warranty.
Complete instructions
Your furnace includes a wiring diagram,
programming instructions, and heat treating manual. The manual gives
you basic heat treating instructions for D2, 440C, ATS 34 and 154 CM.
The manual is written in plain English for the beginner.
Optional Gas Injection Flow Meter
During heat treating, scale forms on the
surface of the steel. One way to eliminate most scaling is to wrap the
steel in stainless steel foil. An easier way is to install the gas
injection flow meter on your furnace. It is available as either an
add-on kit, or you can order the furnace with the meter installed.
The meter regulates the flow of an inert gas,
such as argon, inside the furnace. The gas displaces the oxygen to
prevent most scaling.
