Equipment for in-line measurement of the proportion of austenite in steel

摘要

The present invention relates to an apparatus for electromagnetically measuring the proportion of austenite contained in a continuously moving steel strip during an in-line process for manufacturing or transforming a steel strip in real time. Discharge coil (1). The magnetic field generated by the alternating current flowing through the steel strip (5) produces an induced current in the receiving coil (2), which produces an electromotive force in the receiving coil (2) for voltage measurement. The device (4) can measure this electromotive force, and the amplitude of this electromotive force depends on the voltage applied to the discharge coil (1) and the steel properties of the strip (5). The present apparatus is characterized in that the first coil (1) and the second coil (2) are arranged in parallel with each other at set intervals and are arranged on both sides of the steel strip (5) at the time of use. do.
