The equipment shall provide access to the entrance of the heating
chambers via the following:
•
Entrance Interface Roller (optional)
•
4.3
IR FURNACE
. The IR furnace section shall consist of the following:
4.4
- Entrance Baffle & Exhaust Eductor. The entrance baffle section shall be housed inside an
aluminum shell lined with ceramic fiber insulation. The system shall include a metal air rake
to introduce a gas curtain above the belt. This gas curtain and a series of four equally spaced
hanging baffle gates shall serve to purge the chamber and prevent ambient air from entering the
heating section. A venturi-assisted exhaust stack shall draw gases from the entrance of zone 1,
across a drip tray and out of the furnace to prevent exhaust condensation from falling into the
entrance baffle. Proper operation of this system shall keep the furnace heating section clean.
4.5
Furnace Heating Section
. The heating section shall be comprised of 30 inch (76.2 cm) long
chambers; each chamber shall be partitioned into temperature controlled zones using ceramic
dividers. The dividers shall be configured with the smallest possible opening that can be made
to be consistent with the parts clearance specifications to assure very high thermal isolation
between the zones.
4.5.1.1
Chambers
. Each chamber shall be contained within an aluminum shell lined with
ceramic fiber insulation. Gas introduced into a plenum between the shell and the porous
insulation shall be heated as it passes through the insulation to enter the chamber at chamber
temperature. This method of gas distribution shall not affect the temperature profile, shall assist
in keeping the interior of the furnace clean and shall speed the cool down process when the
lamps are turned off
.
4.5.1.2
Control Zones.
The interior of the furnace chamber shall be partitioned into
controlled zones using ceramic dividers. The dividers shall be designed with the smallest
possible opening that can be made to be consistent with the parts clearance specifications to
assure very high thermal isolation between the zones. The chambers shall be divided into
zones as follows:
