Title:
ソーク時間自動補正および加熱異常自己診断機能を備えた産業用温度制御装置およびその方法
Document Type and Number:
Japanese Patent JP7153404
Kind Code:
B2
Abstract:
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.
