SUBMERGED-ENTRY NOZZLE CENTRING DEVICE

摘要

The present invention relates to an apparatus for centering a submerged entry nozzle. The present invention includes: a plurality of laser beam generators 20 that is disposed above a mold 3 for continuous casting to radiate a laser beam toward the center of the mold; a tundish moving unit 15 that moves a tundish 1 above the mold 3; and a control unit that is linked with the laser beam generators 20 and controls the tundish moving unit 15 to center the installation position of the submerged entry nozzle 5 provided at the lower portion of the tundish, in response to signals transmitted from the laser beam generators 20. According to the present invention, in addition to accurately and quickly centering the submerged entry nozzle 5, it is possible to maintain the submerged entry nozzle that has been centered, such that it is possible to minimize a channeling phenomenon of molten steel. Accordingly, it can be expected to improve the quality of a slab.
