sponding recommendations for these casting
temperatures, which generally have been verified
by empirical tests, are given by the manufacturers of
alloys and casting equipment. With most casting
devices the accuracy for achieving the recom-
mended casting temperature through visual
assessment of the developing temperature still
depends on the individual skills of the user.
In contrast, the new NAUTILUS
®
CC plus casting
device uses an automatic measurement method to
determine the right time to cast, which facilitates an
exact determination of the casting temperature
within a very short period of time and even with only
small amounts of alloy. At the same time the light
information of the melt is evaluated by means of an
optical system and a so-called pyrometer with a
multichannel measuring system and converted into
temperature values. The melting process is
monitored on the basis of the data captured in this
way and casting can be triggered automatically (on
request also manually) after the alloy-specific
casting temperature is reached. The measuring
method applied is able to compensate for influences
due to fluctuations in the light emission of the melt,
such as those occurring when the oxide skin opens
during melting.
This innovative technology inside of the
NAUTILUS
®
CC plus has been used to determine
the perfect casting temperatures of BEGO alloys
and are stored in special casting programs for the
control system. Thanks to the new measuring
technique, it is now possible to determine the
casting temperatures very reliably and on a repro-
ducible basis. The standard values recommended
thus far for the casting temperatures of BEGO alloys
have consequently been adapted to the newly
defined values in some cases and are summarized
in the casting table of this operating manual.
If third party alloys are used with the NAUTILUS
®
CC plus, the casting program of a BEGO alloy with
the closest match with regard to alloy composition
and alloy characteristics can be copied. Now only
the casting temperature and the name of the non-
BEGO alloy have to be adapted according to the
respective manufacturer's specifications. Users can
manually cast non-BEGO alloys, without specified
casting temperatures, according to their visual
impression and then utilize the displayed temper-
ature to create their own casting programs for
automatic operation with these alloys. A casting
program for a non-BEGO alloy in the program
memory of the NAUTILUS
®
CC plus can be set up
in just a few steps and is described in the operating
manual.
NOTE
Tip:
Non-BEGO alloys should first be cast
manually with a pyrometer to check if the casting
temperature specified by the manufacturer is
correct.
