Description
Уже известны устройства дл опред-лени наступлени момента исчезноЕенк магнитных свойств нагреваемой стали. Обычно подобного рода устройства иснользуют вление изменени величины самоиндукции катушки,включенной в соответствующий измерительный контур и помещенной внутри печ;; непосредственно возле нагреваемого стал-ного издели . Исчезновение магнитных свойств последнего при переходе черев критическую точку вызывает резкое изменение величины самоиндукции катушки. При этом нарущаетс равновесие токов в системе, в которую эта катущка включена, в результате чего начинает работать сигнальное приспособление либо измерительный прибор .Already known devices to determine the onset of the moment disappear are the magnetic properties of the heated steel. Usually, such devices use the phenomenon of a change in the value of self-induction of a coil included in the corresponding measuring circuit and placed inside the furnace ;; directly near the heated steel product. The disappearance of the magnetic properties of the latter at the transition through the critical point causes a sharp change in the value of the self-induction of the coil. In this case, the equilibrium of currents in the system in which this coil is turned on is disrupted, as a result of which the signal device or measuring device begins to work.
В предлагаемом, согласно изобретению , устройстве, построекном на том же принципе, в пе./1 х устранени ощибок измерени , возникающих в результате воздействи на работу схемы магнитного ПОЛИ, создаваемого нагревательной обмоткой электрической печи, последн намотана бифил рно.In the device proposed according to the invention, built on the same principle, in ne / 1x the elimination of measurement errors resulting from the effect on the operation of the magnetic POLY circuit generated by the heating winding of an electric furnace, was last wound bifillary.
На чертеже изображена электрическа схема предлагаемого устройствЕ.The drawing shows the electrical circuit of the proposed device.
