Abstract
Устройство для контроля наличия оправки и определения положения стыка трубы в стане холодной прокатки, содержащее генератор, вихретоковый преобразователь, компенсатор, усилитель, первый дискриминатор, фазовращатели, таймеры, инвертор, схему совпадения, интегратор и блок сигнализации, отличающееся тем, что, с целью повышения надежности контроля наличия оправки внутри трубы и определения положения стыка труб из ферромагнитных и парамагнитных материалов, оно снабжено вторым дискриминатором, причем вихретоковый преобразователь выполнен из установленных внутри корпуса индикаторной обмотки, расположенных симметрично относительно нее двух кольцевых и двух сегментных охватывающих половину трубы индукторных обмоток и обмотки подмагничивания, встроенной в корпус и подсоединенной к источнику постоянного тока, при этом кольцевые и сегментные индукторные катушки включены последовательно, а индикаторная обмотка подсоединена к одному входу компенсатора, второй вход которого подсоединен к генератору, а выход - через усилитель к сигнальным входам дискриминаторов, к опорным входам которых подсоединены выходы фазовращателей, выходы дискриминаторов подсоединены к входам таймеров, выход первого таймера подсоединен к первому входу сигнализации и через инвертор к схеме совпадений, выход второго таймера - к второму входу схемы совпадений, выход которой через интегратор подсоединен к второму входу блока сигнализации.A device for controlling the presence of a mandrel and determining the position of a pipe joint in a cold rolling mill, comprising a generator, eddy current transducer, compensator, amplifier, first discriminator, phase shifters, timers, inverter, coincidence circuit, integrator and signaling unit, characterized in that reliability of monitoring the presence of a mandrel inside the pipe and determining the position of the junction of pipes made of ferromagnetic and paramagnetic materials; it is equipped with a second discriminator, the eddy current transducer being made installed inside the case of the indicator winding, located symmetrically with respect to it, two annular and two segment half of the pipe covering the inductor windings and the magnetic biasing winding embedded in the housing and connected to the DC source, the ring and segment inductor coils are connected in series and the indicator winding is connected to one input of the compensator, the second input of which is connected to the generator, and the output, through an amplifier, to the signal inputs of the discriminators, to the reference inputs Odds of which are connected to the outputs of phasers, discriminator outputs are connected to the timer inputs, the output of the first timer is connected to the first alarm input and through an inverter to the coincidence circuit, the output of the second timer to the second input of the coincidence circuit, the output of which is connected to the second input of the alarm unit through the integrator.
