摘要： A method for electromagnetic and real-time measurement of a percentage of austenite contained in a steel strip in continuous motion during in-line manufacture or transformation thereof, by a device including the steel strip and a measuring device including at least: an alternating-current generator; a first coil supplied by the alternating-current generator, called a transmitting coil, and a second coil, called a receiving coil, the first and second coils being arranged parallel to each other or coaxial and on both sides of the steel strip, a distance between the coils being fixed and between 10 and 200 mm; a core of ferromagnetic material being a center of each coil, respectively; and at least one voltage-measuring device connected to terminals of the receiving coil, being a multimeter or an electronic acquisition system having an analog-digital converter coupled to a computer, to obtain the percentage of austenite contained in the steel strip.

摘要： The present invention relates to a device for electromagnetically measuring, in real time, the percentage of austenite contained in a continuously running steel strip during an in-line process for manufacturing or transforming the latter, such that the magnetic field produced by the alternating current flowing through the emitter coil (1) produces, in the steel strip (5), induced currents that generate an induced magnetic field creating, in the receiver coil (2), an electromotive force that can be measured by the voltage measurement device (4), the amplitude of this electromotive force being dependent on the voltage applied to the emitter coil and on the nature of the steel in the strip (5). The device is characterized in that the first and second coils (1, 2) are arranged in parallel to one another with a set distance between them and, in use, on either side of the steel strip (5).

摘要： An electrochemical treatment method includes: implementing an electrolytic cell containing an electrolytic bath; and immersing an electrode and a deformable counter-electrode in the electrolytic bath, both the electrode and the deformable counter-electrode being connected to a source of continuous or pulsed current, the electrode having an electrically-conductive part and the counter-electrode to be brought near the electrode. A geometry of the deformable counter-electrode is adapted automatically, locally, and independently point by point, to a geometry of the electrically-conductive part before the electrochemical treatment is performed.
