Abstract

The problems of construction, reliability in operation, control and maintenance in modern iron and steel mill industry are discussed. The advantages and limitations of traditional inspection methods are evaluated. The results from infrared inspections and field control of reheating furnaces with different construction, damage conditions, before and after retrofitting are analyzed and evaluated. Repeated infrared investigations were performed with short and longwave IR-systems. The results from the investigation indicates that infrared technology has an information potential which could be used for priority measurements within e.g. regular control programs, and as input in development of constructural standards, and for warranty inspection. The research needed to develop accurate and cost-efficient operative methods is discussed. The research project is planned to be continued.
