説明

Water-model experiments have been carried out to understand the behavior of mold powder trapping phenomena by vortex in continuous casting mold. The following findings are obtained.<BR>(1) Mold powder trapping by the vortex occurs irregularly near the immersion nozzle. It occurs only in the wake of the immersion nozzle.<BR>(2) As for the occurrence frequency ratio of the vortex, the maximum value appears in the water flow rate regime ranging from 61.4 to 70.2 L/min. This regime is supposed to have a lose relationship with water flow velocity change near the immersion nozzle.<BR>(3) An empirical equation is proposed for the length of the molten mold powder entrapped by the vortex.
