Rio Tilt-Pour Automatic Melting Furnace
3. Once the temperature set-point is saved, the furnace will quickly
begin to ramp up to that temperature and the red LED “ramping
up” arrow displays. The ramp-up time for the 3kg model to reach
1950°F is around 20 minutes; this time will vary depending upon
the temperature chosen and the amount and type of metal in the
furnace. When the set-point temperature is achieved, the square
green LED will come on. The red LED “overshoot” arrow will appear
next, indicating the furnace has gone slightly beyond the set-point.
The LEDs will alternate off and on as the furnace self-adjusts to the
set-point. Please Note: It is normal for the temperature to fluctuate
slightly above and below the set-point.
4. Using the tongs included with the furnace, grasp the crucible
around the grooves in its upper sleeve (as shown). Carefully
lower the crucible into the heating chamber and close the lid.
Warning! At this time, the heating chamber is extremely
hot. Use caution and always wear heat-resistant gloves when
performing any operation near the heating chamber.The
temperature shown on the display will ramp down slightly
when you first add the crucible. It will return to your set-point
temperature after a few minutes.
5. Beginning with small pieces, slowly add metal to the crucible—
fill the crucible only to ¼–⁄ of its capacity at first. Once that
is melted, add more metal until you have the amount needed
for your casting.
Warning! Use caster’s tweezers to handle the metal pieces.
Do not drop larger, heavier pieces into the crucible as the shock
could fracture it.
Please Note: We recommend using separate crucibles for
different metals to avoid cross-contamination.
6. When you have fully charged the crucible with metal and the
temperature is slightly below set-point, stir the metal with an
appropriate stirring rod (sold separately, see back page). After
the metal has reached casting temperature, open the lid fully
to lock it in position.
7. Grasp the handles at the back and side of the furnace,
keeping your thumb on the lid tab to secure it. Pour
smoothly and quickly into your mold; the metal will
immediately begin to cool. If casting multiple flasks,
repeat as needed.
• Warning! Never tilt the furnace more than 90°; the
crucible can slide out of the furnace spilling hot metal.
• Warning! Always wear appropriate heat-resistant safety
gloves (such as the Kevlar® gloves) whenever you are
handling a hot crucible.
