The paper deals with the approaches, methods and technological features of conducting thermal control of the casing of blast furnace shafts. The causes for formation of the main defects in furnace cooler walls during operation are established. Procedure of comprehensive nondestructive testing, including thermal imaging, of blast furnace armour, is described. Advantages of TV diagnostics of the above-mentioned objects of control are determined. Ways and methods of elimination of the found defects with application of modern technologies are described. 3 Ref., 8 Fig.
