PROBLEM TO BE SOLVED: To provide a commercially advantageous method capable of remarkably evading overcooling at the inside curved part of a preliminary form strand, and to provide a device performing this method. SOLUTION: In the case of a continuous casting method for creating a preliminary form, in particular, a double-T preliminary form, cooling water flowing to the lower part is extruded from the inside curved part of the preliminary form strand (3) via a primary form flange, and, using water nozzles (21, 22) almost positioned from a bar (4) to the respective flanges (5) and (6), and is exhausted by relief water fed out via the water nozzles (21, 22). In this way, overcooling caused by the cooling water flowing to the lower part is remarkably evaded at the inside curved part of the preliminary form strand. COPYRIGHT: (C)2010,JPO&INPIT |
