ABSTRACT:
A radiant furnace for firing ceramic material provides for accurate control over the rate of increase of the ceramic material temperature during a firing operation. Heat is radiated in the furnace from an electrically controlled heater. A first programming signal is produced to represent a manually selected rate at which the temperature is to be raised, and a second programming signal is produced to represent a manually selected target temperature beyond which the ceramic material temperature is not to be raised. Circuitry responsive to the first and second programming signals produces a command signal varying in magnitude to define a ramp having a peak value. The command signal is applied to a closed-loop heating control subsystem employing a thermo-sensitive transducer for providing a feedback signal.
