Abstract
Способ определения топографии слоев футеровки металлургических агрегатов, включающий ультразвуковую низкочастотную локацию слоев футеровки с приемом отраженных ультразвуковых колебаний, регистрацию в запоминающем устройстве резонансного спектра колебаний, установившихся в слоях футеровки от излучателей УЗК и от низкочастотных УЗК, возникающих в слоях футеровки работающего агрегата, по частоте которых с учетом физических свойств материала футеровки в соответствии с математической моделью определяют координаты границ слоев футеровки напротив мест замеров и осуществляют построения топографии футеровки, отличающийся тем, что наряду с приемом установившихся низкочастотных УЗК осуществляют контроль других физических параметров многопараметровыми датчиками, расположенными стационарно по поверхности низкотемпературной части футеровки или внутри ее на расстоянии от этой поверхности, для каждого параметра строят соответствующую математическую модель, на основе каждой модели осуществляют построение топографии футеровки, затем модели проверяют на корреляционную связь, после этого осуществляют построение окончательной топографии футеровки, причем расстояние между датчиками определяется размерами металлургического агрегата и толщиной футеровки.A method for determining the topography of the lining layers of metallurgical units, including ultrasonic low-frequency location of the lining layers with the reception of reflected ultrasonic vibrations, recording in the storage device the resonance spectrum of vibrations that are established in the lining layers from the ultrasonic transducers and from the low-frequency ultrasonic vibrations arising in the lining layers of the working unit, whose frequency taking into account the physical properties of the lining material in accordance with the mathematical model determine the coordinates of the boundaries of the layers of the foot They are in front of the measurement sites and construct the lining topography, characterized in that, along with the reception of established low-frequency ultrasonic testing, they control other physical parameters with multi-parameter sensors located stationary on the surface of the low-temperature part of the lining or inside it at a distance from this surface, for each parameter, the corresponding mathematical model, based on each model, the construction of the topography of the lining is carried out, then the models are checked for correlation connection, after this, the final topography of the lining is constructed, and the distance between the sensors is determined by the dimensions of the metallurgical unit and the thickness of the lining.
