FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and is intended for the determination of the topography of lining layers in a metallurgical facility. The method involves acoustic radar location of the layers of lining in an operating facility with the reception of the reflected vibrations by acoustic vibration sensors, registration of the vibration resonance spectrum in a memory unit with the vibrations being set in the lining layers from the acoustic vibration transmitters and from acoustic vibrations occurring in the lining layers of the operating facility, on the basis of the frequency of the registered reflected acoustic vibrations accounting for the physical properties of the lining material and according to the mathematical model the coordinates of lining layers' borders are determined opposite the measurement points and the topography of the lining layers is created. Additionally the lining temperature is measured by temperature sensors and elastic stresses in the facility housing are measured by strain sensors, basing on the above the respective additional lining layers' topography is created with the help of mathematical model. The said sensors are set stationary on the housing surface with the specified distance between them in vertical and horizontal directions with the distance being defined by the facility size and the lining thickness. The final topography is created on the basis of the mutual correction of the obtained topographies using the correlation relationships between them.
EFFECT: use of the invention provides for higher accuracy of creating the topography of metallurgic facility lining.
