Abstract (en)
[origin: EP2226139A1] During the continuous casting process, cooling water is introduced against the web and side flanges of the strand, and is removed from the curved region of the strand. The downwardly-flowing cooling water is ejected by deflection water jets from nozzles (21, 22). These are directed at the transitions between the web (4) of the I-beam and its flanges (5, 6). The jets force the water out and over the flanges, to be led away. Cooling water displaced or sprayed out from the inner curve, together with the jetted deflection water, is removed and led away by an interceptor (23). Deflection water nozzles are employed in the initial, still-vertical region of the curved strand guidance system. Where the guidance system has many components, the deflection water is introduced into the preliminary strand profile in the region between the first two of them. It is introduced approximately in the central zone of the curved strand guide at an angle of 0[deg] to 90[deg] , preferably about 45[deg] to the curve tangent in the strand. The nozzles lie in a common plane; this includes an angle of 0[deg] to 90[deg] with the curve tangent. The nozzles can be moved transversely back and forth relative to the side flanges of the strand. The additional cooling effect of deflection water is compensated by reduction in the amount of downwardly-flowing cooling water. To prevent sub-cooling of the strand, the deflection water is pre-heated. To control the deflection water temperature, the cooling of the strand is varied. An independent claim IS INCLUDED FOR corresponding continuous casting equipment.
