ADVICES - PRECAUTIONS FOR USE
GENERAL
-
During operation and after use, the surface of
the furnace head may become very hot: avoid
direct contact
with the skin
(risk of burns).
-
eON sinter fast + is equipped with
heat
extractors
to control the temperature of the
components and guarantee safety:
do not
cover the furnace during use
and
do not place
objects
around the furnace or in front of the
ventilation openings.
CYCLE START AND CONFIGURATION
-
Do not open the platform during high
temperature cycles
: danger of burns and risk of
irreversible damage to heating elements and
refractories.
-
At the end of the cycle,
the temperature must
be lower than 300°C before opening the
furnace. Do not switch off the power supply
,
because heat extractors are stopped and the
internal temperature increases and can
damage the equipment.
-
If the
temperature is above 300°C, it is not
possible to start a cycle
(risk of damaging the
refractories.) Wait for cooling: temperature
displayed on the screen below 300°C.
-
When the
temperature is below 200°C, the
power supply can be switched off
(switch at
the back of furnace).
-
At the end of the cycle, the furnace
automatically returns to the
standby position
.
-
When the
furnace is in standby or off, the
platform must be in the high position
to avoid
condensation.
-
Do not touch the display during a cycle
to
avoid manual interruption of the programme.
-
At the start of the cycle, avoid using an
increase rate too fast
to avoid damaging the
heating elements. Likewise,
a large difference
between two increase rates is not
recommended.
-
Observe the recommendations of the
manufacturer of Zirconia
to avoid significant
gaseous emissions which may damage the
muffle.
-
For the first time or after a long time without
use, need to
preheat
to eliminate condensation
and avoid fractures of the refractory material:
launch a decontamination program (No. 40).
-
Zirconia sintering temperatures are given as
indicative by disc manufacturer.
If necessary,
these one can be adjusted from -15°C and up
to +50°C around the final temperature
recommended.
-
Comply with the recommendations of the
manufacturer of the zirconia used to verify
compatibility with the perform of a short
program and the maximum number of
elements in short cycle
. Follow its instructions
for programming within the technical limits of
the e.ON sinter fast + (
the value of the heating
rate must be less than 94°C /min up to 1000°C).
HEATING ELEMENTS (RODS)
-
Molybdenum silicon rods are very brittle at
room temperature:
do not handle them.
-
The
heating
elements must not be maintained
for long periods between 400°C and 700°C
to
avoid their oxidation.
