Basic principles: Crucible
Adjusting the crucible locking device
Burn hazard from hot parts!
• Always use mould tongs to move
hot crucibles.
• Always use mould tongs to move
hot crucible inserts!
The crucible in use can be locked in its position by
means of the crucible locking device, thus ensuring
that the melt is safely drained by the centrifugal
force.
1. Loosen the wing screw on the crucible lock.
The crucible locking device can now be
adjusted.
2. Pull die crucible locking device backwards
using the wing screw.
3. Insert and align the crucible so that the outlet
of the crucible fits into the opening provided for
that purpose.
4. Push the wing screw back towards the crucible
so that the crucible locking device is locked in
its position.
5. Tighten the wing screw.
Fornax ceramic crucibles (RE 52483) do not
need to be preheated before casting.

Filling the crucible
NOTICE
NOTICE
English ⋅ Fornax® T
1. Fill the desired alloy into the clamped crucible.
2. In the case of special alloys, sprinkle a pinch of
BEGO Auromelt HF melting powder on the
alloy (see table on page 26).
Melting powder made by other manufacturers
may impair the casting result!!
Auromelt HF should be used very sparingly
(only a pinch)!
ATTENTION!
• Observe minimum and maximum quantities!
3. Depending on the selected alloy, place an
additional graphite insert (REF 52454), glassy
carbon insert (REF 54883) or ceramic insert
(REF 52455) into the ceramic crucible during
the melting process (see casting table
page 26)!
Alloys with a high palladium content are generally
casted in a ceramic insert. A glassy carbon insert
can be used if the alloy chips rise during the
heating process and thus do not have the proper
temperature (failed "incorporation" in the
induction field):
• with palladium contents up to 30% of the graphite insert,
• with palladium contents over 30% of the glassy
carbon insert, which reliably prevents carbon
from being absorbed by the alloy.
Pile alloy plates loosely into the ceramic crucible as
it may otherwise crack during heating!
Recommendation: Fill in old metal first, top off with
new metal.
Always use crucible and inserts for the same alloy.
Crucibles can be written on with a pencil.

Operation
Preheating
Premelting is necessary to keep the "cast delay
time" (time to melt the alloy after insertion of the
mould) as short as possible.
1. Align the crucible with the center of the crucible
coil by turning the casting arm and moving the
the slider back and forth.
2. Lift the crucible coil. Pull the handle located on
the right exterior side of the device forward for
this purpose.
3. To avoid fusing, the knob must be set to up to
50% according to the alloy-specific value. The
setting controls the switching of the heater on
and off according to the measured IR radiation
of the alloy.
4. The preheating process is started by closing
the cover.
The "heating" button will light up to indicate
that the heating process is in progress
Never look into the melt without
protective glass and protective
eyewear!
ATTENTION!
• Do not premelt the alloy for too long as this may
result in uncharacteristic behaviour of the alloy
later on.
During the premelting process, the castings
should only deform slightly and not melt completely!
• As these are only reference values, the castings must be observed. If the castings deform
more than just slightly, the premelting process
must be stopped (and the value setting must be
reduce with the knob).
• Do not move the handle to raise/lower the crucible coil during the premelting process as this
will initiate the spinning process prematurely!
5. Open the cover to stop the premelting process.
The heating process will be interrupted.

Melting
Ideally, the melting process should always be
carried out at the max. setting (knob to 100%)!
In isolated cases, the premelting and melting
process may be carried out with a reduced setting.
The corresponding values must be individually
determined by the user and can be entered into the
table on page 26. The corresponding procedure
also applies for non-Bego alloys.
Melting procedure
When the last solid part has sunk completely into
the melt, continue to heat as long as is indicated in
the table on page 26!
After the end of the further heating time casting can
be carried out, provided that the melt is ready for
casting after a visual check. The time needs to be
used for an exact setting of the continuous heating
time during the melting process.
Important!
The motion of the melt is caused by the magnetic
field, not by the heat. The moving melt is
therefore not a "boiling" melt!
1. Align the crucible with the center of the crucible
coil by turning the casting arm and moving the
the slider back and forth.
2. Lift the crucible coil. Pull the handle located on
the right exterior side of the device forward for
this purpose.
3. Insert the preheated mould into the mould
holder. The pouring spout of the mould must
face towards the crucible (page 21/22).
4. The melting process is started by closing the
cover.
The "heating" button will light up to indicate
that the heating process is in progress
5. For the melting process, turn the knob to the
max. heating setting (100%) or to the individually determined heat output, respectively.
24
Never look into the melt without
protective glass and protective
eyewear!
6. Look through the protective lens to observe the
melt.
7. Start the timer (with the continuous heating/
holding time entered in the casting table page
26) when the last solid part has completely
sunk into the melting bath.
