The working principle of the sensor

The sensor adopts the principle of electromagnetic induction for signal detection, and its typical structure is two concentric coils. When the primary coil is supplied with an intermediate frequency excitation current, due to the action of the magnetic field, an eddy current is generated in the steel flow, and the direction of the magnetic field is opposite to the direction of the magnetic field generated by the coil. Because the conductivity of slag is much lower than that of molten steel at high temperature (about 1/1000), the eddy currents generated in slag are much smaller than those generated in molten steel. In the process of pouring steel, all the molten steel flows out at the beginning of pouring. At the later stage of pouring, there will bemakingingThe principle of sensor construction

The primary coil and the secondary coil are isolated by high temperature resistant materials, and s are. ThenThe installation of the sensor

The sensor is installed in the ladle reference plate, coaxial with the ladle nozzle, and acts as a guide part for the ladle nozzle casing tube The technical indexes
