The inventive enhancement method 1 is reliable and devices

FIG. 1 shows a block diagram of the device; in fig. 2 plate sections of the partitioned electrode; in fig. 3 cylindrical sections of a sectioned electrode.

The device has a means for detecting megalonic inclusions 1, consisting of a sectioned electrode 2 and a nonseparated electrode 3 located on opposite sides of material 4. Each section of the sectioned electrode 2 is spring-loaded relative to material 4 and provided with a high voltage source 5 that includes an adjustable power supply unit 6 and a high voltage converter 7, the output of which is connected to the corresponding section of the partitioned electrode 2, and the input to the output of the power supply unit 6 and the information} input co. sponds re1istra shearing unit 8 shift registers. The clock inputs of the shift registers 8 are supplied with clock pulses. From the sensor 9 of the movement of material 4, for example, reed-type. The power supply unit 6 may be a parametric stabilizer of direct current with an adjustable output voltage and protection against short circuit output. Conversion “) The high-voltage device 7 can be made in the form of H (multiply the gel by one.

By means of detecting metallic inclusions in the course of movement of material 4, means 10 for localizing the sampling zone of metallic inclusions are made in the form of a sectioned frame 11. The shape and location of sections of which corresponds to the shape and location of sections of a sectioned electrode 2. Each section of a sectioned frame 11 is equipped with a display element 12, which can be made in the form of e. 1kgricheskoy bulbs. The device also contains a first pair 13, driven by the movement of the drive 14 of the material 4, controlled by C) by the block 15 of the control of the shadow. The device also includes a service platform 16. The outputs of the shifting registers 8 are connected with the indicating elements 12 of the sections of the partitioned frame 11, as well as with the input of the control unit 14 of the material movement 14 4. Structurally the indicating elements 12 are located at the corresponding sections of the sectioned frame 11 The shape of the sections of the partitioned electrode 2 can have several modifications: performing sections in the form of

plates (Fig. 1) having the shape of a trapezium (the distance between the sections is chosen so as to avoid the "dead zone, for which an overlap 6 is created); the arrangement of the rectangular electrodes in a slaty order (phi1.2), which is necessary to ensure overlap 6; the implementation of sections in the form of 4 cylinders freely rolling along the surface of the base (FIG. 3), the arrangement of which is similar to the arrangement of the sections shown in FIG. 2

The device works as follows.

When the actuator 14 moves the material 4 is turned on, the zero pair 13 drives the material 4 in motion. The material 4 passes between parallel non-sectioned 3 and sectioned 2 electrodes and under the sectioned frame 11. When switching on regulated power supply units 6, the power supply units 7 high voltage, a high voltage voltage appears on the electrodes 2 and 3, a probing spark gap. It is chosen such that the magnitude of the electrostatic field intensity between electrodes 2 and 3 is on the verge of electrical breakdown. The material displacement sensor 9 outputs clock pulses to the clock inputs of the shift registers 8, but since the information inputs of the shift registers 8 do not receive a signal, the registers are in the initial zero state.

When metal inclusions in the thickness or on the surface of the material 4 between the non-sectioned electrode 3 and one of the sections of the partitioned electrode 2, the dielectric constant of the intersectional gap changes and the spark occurs, the corresponding block 6 is protected. power and its output is set to a voltage close to zero. Thus, the information input of the shift register 8 connected to the output of the power supply unit 6 appears as a voltage taken as an information unit, which triggers this shift register 8. The signal transit time of the shift register 8 is determined by the number of clock pulses from the displacement sensor 9 material 4, i.e. the distance that the metal inclusion must travel in order to take place under the corresponding section of the partitioned frame 11. At this moment the signal from the output of the corresponding shift register 8 is fed to the indicating element 12 and to the input of the control unit 15 by the drive J 14 material 4, which disables the drive. A metallic inclusion localized within a specific section of the partitioned frame 11 is detected

is removed and removed manually. Then, the material transfer actuator 14 is turned on 4 and the cycle is repeated.

In case metal inclusions appear under several sections of sectioned electrode 2, the first of the inclusions of metal inclusions is initially indicated, and in the shift register 8 corresponding to the following metal inclusion, information is also stored after the removal of the first metal switching on and turning on the material movement drive 14, the clocking pulses from the material movement sensor 9, 4, activates this register.
