INDUSTRIAL TEMPERATURE CONTROL DEVICE HAVING AUTOMATIC SOAK TIME CORRECTION AND SELF-DIAGNOSING HEATING ANOMALY FUNCTION, AND METHOD THEREFOR

摘要

Provided is a temperature controllers for an industrial heating apparatus including a chamber accommodating a heating target, a heater inputting thermal energy to heat an interior of the chamber, a control temperature sensor measuring the temperature of the chamber interior, and a controller detecting a variation of the input thermal energy and adjusting a soak time on the basis of the variation of the thermal energy. Accordingly, since a temperature equalization time point prior to a thermal equilibrium time point of the center is determined by reflecting an temperature tolerance in the chamber and a soak time is corrected and since the temperature equalization time point is set on the basis of a full load state in which the variation of the input thermal energy per time is the smallest, the temperature at the center falls within an allowable upper/lower limit range even a partial load state is applied, whereby the temperature control apparatus and method for an industrial heater applicable regardless of amount of a heating target may be provided.
