OPERATING INSTRUCTIONS
To test the operation of the unit, apply the following procedure:
(a) Use dummy carbon mold
(b) Place approximately 30 grams (1 oz) chrome-cobalt alloy in the crucible
(c)
Adjust counter-weight to balance centrifuge
(d) Set temperature for 2820°F (1549°C)
(e)
Set Automatic/Manual key switch to Automatic
(f)
Set soak Timer for 10 seconds
(g) Set Centrifuge Acceleration Reducer to 50%
(h)
Set Melt Power Selector to position 3
(i)
Raise the Melt coil to the Up and locked position
(j)
Place the optical pyrometer to the back sighting position.
(k)
Close the centrifuge cover
(l)
Press the Start Button. The alloy should melt within 40 seconds
(m) Press Soak Timer Engage Button when melt reaches temperature
(n)
When soaking time has expired, Melt Coil will drop, centrifuge arm will spin and cast
the molten alloy into the dummy mold; spin for 30 seconds and stop.
(o) Open centrifuge cover
(p) Remove crucible with tongs and clean out slag on tray provided.
NOTE:
Do not clean or de-slag crucible while in crucible holder.
