PROBLEM TO BE SOLVED: To provide a method for monitoring a steel shell of an iron manufacturing container, which dispenses with expensive equipment investment and is applied to the moving container for iron manufacturing without problems. SOLUTION: In this method for monitoring the steel shell of the iron manufacturing container, a substance irreversibly changing at a prescribed temperature or higher, is disposed while being kept into contact with the outer surface of the steel shell of the iron manufacturing container lined with a refractory inside thereof, and the temperature of the steel shell of the iron manufacturing container is estimated on the basis of an irreversible change in the substance irreversibly changing. Here, the irreversibly-changing substance is a coating material, and the irreversibly-changing substance is preferably a substance irreversibly changing at 400°C or higher.
