Description
Изобретение относитс к контролю нарушений технологических процессов в дуговых сталеплавильных печахг в частности индикации аварийного состо ни подины.The invention relates to the control of process disturbances in arc steel-smelting furnaces, in particular the indication of the emergency state of the hearth.
Известно устройство дл контрол состо ни подины, в котором датчик износа состоит из трубчатого корпуса, монтируемого в футеровке печи, причем конец корпуса, устанавливаемый в футеровке, герметизирован, а на внешнем конце располсэжена герметически сочлененна с корпусом сжата камера из упругого материала типарезины , выполненна с возможностью изменени формы при разгерМетизации второго конца датчика. При процессе износа футеровки прбисходит разгерметизаци конца датчика, монтируемого в футеровку , и сжата камера измен ет свою форму на шарбойразную. сигнализиру об износе;ф у ёровки 1.A device for monitoring the state of the bottom is known, in which the wear sensor consists of a tubular body mounted in the furnace lining, the end of the body installed in the lining sealed, and the outer end of the case is hermetically articulated with the body compressed chamber of elastic material such as rubber made the ability to change shape when the second end of the sensor is depressurized. During the lining wear process, the end of the sensor mounted in the lining is depressurized, and the chamber is compressed and changes its shape to sharaboraznaya. wear signal; 1 f.
При монтаже такого устройства в ДСП снижаетс надежность и устойчивость футеровки. Конструктивно датчик сложен. Контроль футеровки ведетс локально, в одном месте, т.е. дл контрол состо ни всей футеровки требуетс -р д датчиков, чтоWhen mounting such a device in a chipboard, the reliability and stability of the lining is reduced. Structurally, the sensor is folded. Lining control is carried out locally, in one place, i.e. To monitor the state of the entire lining, a range of sensors is required, which
значительно снижает надежность и устойчивость футеровки.significantly reduces the reliability and stability of the lining.
Наиболее близким к предлагаемому по технической сущности вл етс устройство контрол состо ни подины. Устройство содержит последовательно соединенные источник Задающего напр жени и датчик тока, причем один из выводов последовательной цепи Closest to the proposed technical entity is a device for monitoring the state of the hearth. The device contains a series-connected voltage source and a current sensor, one of the terminals of the series circuit

При прожоге подины ее сопротивление (между расплавленным металлом и корпусом) резко уменьшаетс , при этом увеличиваетс ток в цепи 10 is attached to the body of an arc steel-smelting furnace, and the other is connected to a bottom-ground product making contact with the molten metal. The output of the current sensor through the threshold device 15 is connected to the alarm device. When the bottom is burned through, its resistance (between the molten metal and the body) decreases sharply, and the current in the circuit increases.
