Preparation
1. Determine the following values from the manu-
facturer's specifications (processing instruc-
tions, data sheet):
• the three most important alloying compo-
nents,
• casting temperature,
• processing requirements (melting with
graphite inserts, use of melting powder, etc.)
2. Find the BEGO alloy that corresponds most
closely. Sources:See BEGO precious metal
alloys table, BEGO catalog or the information
on alloys available in the download center at
www.bego.com.
3. Determine the program number of the suitable
BEGO alloy from the program table on
page 34.
Casting
1. Cast the non-BEGO alloy manually with
pyrometer (see page 35 ff). Use the program
number of the identified BEGO alloy for that
purpose.
2. If necessary, adapt the casting temperature
displayed on the screen to the manufacturer's
specification. Select the highest casting tem-
perature of the recommended casting ranges.
3. Observe the specifications provided in the
operating instructions starting on page 35, like
holding times during the melting process, etc.
4. Note the casting temperature indicated when
casting is triggered. It is required for setting up
the program for the non-BEGO alloy.
Creating programs
Programs 181 to 186 should be used for non-
BEGO alloys without precious metals, which
tend to splatter when heated under vacuum,
because with these programs the alloys are
casted with reduced vacuum. Programs 191 to
193 use the maximum vacuum and are thus not
suited for such alloys.
1. Press the button with the preselected alloy in
the main menu.
The alloy selection menu will be called up.
2. Press "New" to create/set up a new casting
program.
3. Press the "Find alloy" button.
