Filling the crucible
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)!
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)!
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.
NOTICE
ATTENTION!
• Observe minimum and maximum quantities!
NOTICE
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 graph-
ite insert,
• with palladium contents over 30% of the glassy
carbon insert, which reliably prevents carbon
from being absorbed by the alloy.
