摘要： PROBLEM TO BE SOLVED: To realize a method for evaluating the physical properties of a regular shape refractory product composed of more than one kind of material having different thermal conductivity nondestructively and accurately by heating the refractory product up to a predetermined inspection temperature and making an evaluation based on the temperature distribution shown by a thermographic image. SOLUTION: A thermography performs noncontact measurement of infrared energy radiated from a regular shape refractories to determine the infrared intensity distribution, i.e., the temperature distribution, imagewise. Obtained data is delivered to a data processing section in order to evaluate the physical properties of the regular shape refractories. Since the infrared wavelength region to be observed can be limited, reliability of measurement can be enhanced and since the data can be preserved, measurement conditions can be generalized and a long term evaluation can also be made. A given temperature variation is imparted to an object and the heat shock resistance is evaluated, based on the variation data of temperature with time for the entire object. When the shape or the material of a refractory product is modified, the effect of modification onto the heat shock resistance can be evaluated nondestructively.
