Description
вторичной обмотками, соединенными в мостовую схему.secondary windings connected in a bridge circuit.
На фиг. 1 изображен общий вид датчика , установленного на клети; на фиг. 2-индукционный преобразователь в полости контролького калибра с одной из возможных ирниципиальных схем подключени рабочих головок и средств визуального контрол .FIG. 1 shows a general view of the sensor mounted on the cage; in fig. A 2-induction transducer in the cavity of the inspection caliber with one of the possible irsimensional diagrams for the connection of the working heads and means of visual control.
На брусе 1 прокатной клети в полости контрольного калибра пр моугольной формы при помопди основани 2 и кронштейна 3 размещают индукционные преобразователи 4 и 5. Каждый из них имеет две рабочие головки 6, расположенные против стенок контрольного калибра. Рабочие головки снабжены первичными 7 и вторичной 8 обмотками. Средства 9 контрол (например, цифровой индикатор) подключены ко вторичной обмотке по мостовой схеме с компенсационным блоком 10 и трансформатором 1.1, предусматривающей возможность подключени средств автоматического управлени исполнительными механизмами.On the bar 1 of the rolling stand, inductive transducers 4 and 5 are placed in the cavity of the rectangular-shaped control caliper when the base 2 and the bracket 3 are placed. Each of them has two working heads 6 located opposite the walls of the reference caliber. The working heads are equipped with primary 7 and secondary 8 windings. Control means 9 (for example, a digital indicator) are connected to the secondary winding by a bridge circuit with a compensation unit 10 and a transformer 1.1, which provides for the possibility of connecting means for automatic control of actuators.
Контроль осевого смещени валков ирн помощи предложенного датчика производ т следующим образом.The control of the axial displacement of the rolls by means of the proposed sensor is performed as follows.
При равенстве зазоров между рабочими головками датчика и стенками контрольного калибра наблюдаетс равновесие в системе, т. е. ЭДС, наведенные во вторичной обмотке равны нулю. При смещении валка в ту или иную сторону происходит нарушение баланса магнитных потоков во вторичной обмотке и в ней наводитс ЭДС, котора регистрируетс показывающим прибором. При смещении валка Б другую сторону ЭДС измен етс на 180°, т. е. можно судить не только о величине, по и о направлении смещени With equal gaps between the sensor working heads and the walls of the control gauge, an equilibrium is observed in the system, i.e. the emf induced in the secondary winding is zero. When the roll is displaced in one direction or another, the balance of magnetic flux in the secondary winding is disturbed and an emf is induced in it, which is recorded by the indicating device. When the roll B is displaced, the other side of the EMF changes by 180 °, i.e. it is possible to judge not only the magnitude, but also the direction of the displacement

Так как в предложенном датчике осуществл етс дифференцированное подключение рабочих головок к средствам контрол , значительно повышаетс его точность , Х1арактеристика приблил аетс к линейной , т. е. по вл етс возможность автоматической коррекции осевого смещени валков. Повышение точности контрол до 0,01-0,02 мм в сочетании с автоматической композицией позволит уменьшить колебани проката по овальности профил ,Since in the proposed sensor a differential connection of the working heads to the means of control is carried out, its accuracy is greatly improved, the characteristic is close to linear, i.e., the possibility of automatic correction of the axial displacement of the rolls appears. Increasing the accuracy of control to 0.01-0.02 mm in combination with an automatic composition will reduce the fluctuations in the rolled ovality of the profile,
