Programming
A firing segment
An ST315B firing segment comprises a ramp followed by a soak period.
Two segments can be used for simple firing (biscuit firing for example) or
up to 9 segments can be used per program for complex firing (crystal glaz-
ing or glass
-
making for example).
The ST315B ramps the kiln temperature at the required ramp rate until the
kiln reaches the soak temperature. It then soaks (dwells) at the soak tem-
perature for the soak time. It then runs the next segment until the end of
the program is reached.
The ST315B is capable of both positive (heating) ramps and negative
(cooling) ramps
-
as used in glassmaking for annealing. The type of ramp
is clearly shown on the mimic display during firing.
The ramp rate is settable in the range 1°C/hour to 999°C/hour or
(full power) or
(end of program).
The soak temperature is settable over the range 0 to 1400°C.
The soak time is settable over the range 00.00 (no soak) to 99 hours 59
mins.
Note: during soaking the ST315B display alternates every 5 seconds
between kiln temperature and soak time remaining.
