Creating a new program for shock heat investment materials
1.-3. → page 38.
4 Call up and set the parameters at holding
level 1:
• heating-up speed: 0°C/min. (= max.)
• temperature of the holding level: see invest-
ment material
• duration of the holding level: see investment
material
Set the parameters of holding levels 2, 3 and 4
to zero.
5. Press to set the extraction system to con-
tinuous operation. The display shows „SH”
(shock heat).
(Press again to deactivate.)
6. Exit the programming mode:
Keep depressed until the LED „°C” lights
up.
Hazard from Shock heat
investment materials
So-called shock heat investment
materials are not heated up slowly,
but are placed in a furnace that has
been preheated to the final temper-
ature. As a result, the modelling
material burns atypically, i.e., if the
furnace door is opened, inflowing
oxygen can cause a darting flame!
• Place all moulds in the furnace
within 10 seconds - then keep the
furnace door closed for 15 minutes!
The cut-out of the Regulus furnace
extraction system is set to 600°C at
the factory. Shock heat investment
materials are placed in the furnace at
a higher temperature and produce
concentrated smoke gases in a short
space of time.
• For shock heat investment materi-
als, the Regulus furnace extraction
system (REF 25750) must be
installed.
• Regulus must be set to continuous
operation (see below).
