Abstract
The present invention relates to a method and apparatus for setting heating conditions in a heating furnace wherein a temperature distribution of an object to be heated is measured required minimum times and thermal analysis for the object is performed, thereby optimally heating the object. When the object to be heated is heated by means of a plurality of heating sources in the heating furnace, heating conditions are set to the heating sources respectively, the object is heated, a temperature of the heated object is then detected at a plurality of detection points, a relationship between a variation in the heating conditions in one of the heating sources and a variation in a detected temperature at each of the detection points of the heated object is computed for each heating source, heating conditions in the heating source for causing the detection point of the heated object to have a target temperature are calculated based on the computed relationship, and the heating sources are controlled on the calculated heating conditions.
