The article analyses the main methods for determining the residual resource of these aggregates. Considering the imperfection of the above methods for estimating the residual resource, a method was developed for determining the residual resource of the linings of high-temperature units. The main parameters, which influence the residual resource of the lining, were determined during the operation of the units. In order to take into consideration the influence of temperature stresses on the residual resource of the sintering furnace, we examined a schedule for heating the furnace after an overhaul and calculated the temperature stresses that occur during heating and compared them with the acceptable values. Considering the temperature of the working medium, which exceeded the calculated one – was made according to the records of the operation logs. In general, the obtained result reflects a picture of the actual operation of the sintering furnace between its repairs. For its implementation into real operation, it is necessary to combine a number of measuring processes into a single information complex: a continuous measurement of the lining temperatures during heating; a burner performance (from the position of the torch profile and fuel oil spills); the quality of the resulting technological cakes, etc.
