Изобретение относитс к области темиературного контрол в металлургической промышленности , в частности температуры металла в конвертере.The invention relates to the field of temperature control in the metallurgical industry, in particular the temperature of the metal in the converter.
Известен сиособ 1 контрол температуры жидкого металла в плавильном агрегате путем измерени температуры в нескольких точках футеровки агрегата, иаход щихс на различном рассто нии от расплава, с последующим вычислением в счетно-решающем блоке искомой температуры по известной зависимости . Однако такой способ не учитывает изменение иространственных координат контролируемых точек вследствие изиоса или ошлаковани пограничного сло футеровки. The method 1 for monitoring the temperature of a liquid metal in a melting unit is known by measuring the temperature at several points of the unit lining, which are located at different distances from the melt, and then calculating the desired temperature in a counting unit based on the known dependence. However, this method does not take into account the change in the spatial coordinates of the controlled points due to iosios or slagging the boundary lining layer.
Наиболее близким к оиисываемому изобретению по технической сущности и достигаемому результату вл етс способ 2, в котором измер ют температуру в нескольких точках футеровки, а уточнеиие пространственных координат контролируемых точек футеровки производ т с помощью измерени времени реакции термодатчиков в данных точках на темиературиое возмущение на огневой поверхности футеровки, вызванное, например , вводом присадки. Однако в случае ошлаковани футеровки термодатчики зачастую не реагируют на возмущени , имеющие место на огневой поверхности футеровки от ввода регламентированного технологическим The closest to the invention by the technical essence and the achieved result is method 2, in which the temperature is measured at several points of the lining, and the spatial coordinates of the controlled points of the lining are measured by measuring the reaction time of thermal sensors at these points on the temperature disturbance on the hot surface lining caused, for example, by the addition of an additive. However, in the case of lining the lining, thermal sensors often do not react to disturbances that occur on the lining firing surface from entering a regulated process
процессом количества ирисадки, а сам процесс измерени времеии реакции термодатчика на возмущеии средствами автоматики представл ет больщие трудности, так как медленно измен ющиес иараметры per iCTрировать с высокой степенью точности практически невозможно.the process of the amount of irradiation, and the process of measuring the reaction time of the temperature sensor on the disturbed by means of automation presents great difficulties, since it is almost impossible to periCT the slowly varying parameters and irameters with a high degree of accuracy.
Цель изобретени - получение более точного и надежного контрол температуры металла в конвертере. Это достигаетс тем, что дополнительно измер ют электросопротивление иограничного сло футеровки на участке от одной из контролируемых точек до огневой поверхности и путем обработки информации в счетно-решающем Олоке определ ют температуру металла.The purpose of the invention is to obtain more accurate and reliable control of the temperature of the metal in the converter. This is achieved by additionally measuring the electrical resistance and the boundary layer of the lining in the area from one of the controlled points to the fire surface, and by processing the information in the counting Olok the temperature of the metal is determined.
