Secondary cooling control sensor of the continuous casting device, the dummy bar provided with the sensor and the control method of the continuous casting device

摘要

The invention relates to a sensor of the control of the secondary cooling of a continuous casting machine which comprises the ramps of secondary cooling of the diffusers of water and arranged in the alleys between the rollers, said sensor being driven so as to circulate in front of the cooling ramps, characterized in that it is constituted by a sealed enclosure (1) of small volume, which has a wall (3) of insulating material provided with a pad (12) is thermally conductive, which is arranged so as to face the cooling ramps during the movement of the sensor, the other walls of said enclosure (1) being thermally insulating, in that at least one electrical resistance (6,7) of the heating is arranged in said enclosure, in that the resistors (6,7) are controlled so as to regulate the temperature in said enclosure to a reference value and in that it comprises a sensor (11) of the temperature is disposed in said sealed enclosure.
