Description
Изобретение относитс к черной металлургии , конкретнее к контролю состо ни огнеупорной футеровки.The invention relates to ferrous metallurgy, and more specifically to the control of the refractory lining condition.
Известны способы контрол состо ни футеровки плавильных агрегатов, включаюшие измерение электросопротивлени , емкости или других электрических параметров между металлом и электродами, равномерно установленными в футеровке на равном рассто нии от огневой поверхности .Methods are known for monitoring the state of the lining of melting units, including the measurement of electrical resistivity, capacitance, or other electrical parameters between the metal and the electrodes, which are uniformly set in the lining at an equal distance from the hot face.
к недостаткам известных способов относитс низка точность контрол , св занна с тем, что разрушение футеровки . наступает за счет образовани локальных трещин в футеровке , а контролируют толко интегральный электрический параметр.The disadvantages of the known methods are low control accuracy, due to the fact that the destruction of the lining. occurs due to the formation of local cracks in the lining, and only the integral electrical parameter is controlled.
Цель изобретени состоит в повышении точности контрол .The purpose of the invention is to improve the accuracy of the control.
Поставленна цель достигаетс тем,The goal is achieved by
что измер ют электрический параметр между каждым электродом и металлом, определ ют среднее арифметическое значение параметров, а сигнал разности экстремального и среднего арифметическоthat an electrical parameter is measured between each electrode and a metal, the arithmetic average of the parameters is determined, and the difference signal of the extreme and arithmetic average
го значени параметров после усилени подают на сигнализирук цее и измерительное устройства.After amplification, the value of the parameters is supplied to the signaling device and the measuring device.
В качестве электрического параметра может быть использована проводимость или емкость между металлической ванной и электродами.Conductivity or capacitance between the metal bath and the electrodes can be used as an electrical parameter.
При образовании локальных трещин и заполнении i .их металлом электрический параметр между металлом и ближайшими к трещинам электродами измен етс . Это приводит к различному изменению экстремального и среднего значени электричес- кого параметра. При достижении заранее заданной ра.зности между этими .значел ни ми подают аварийный сигнал и отключают питание печи.With the formation of local cracks and the filling of i. With their metal, the electrical parameter between the metal and the electrodes closest to the cracks changes. This leads to a different change in the extreme and average values of the electrical parameter. When the predetermined difference between these values is reached, an alarm is signaled and the furnace is turned off.
