Abstract (en)
[origin: EP2937162A1] A hybrid cooling nozzle apparatus is provided. The apparatus includes hybrid nozzles provided in a segment of a continuous casting machine to spray cooling water in a mist-spraying mode or a water-jet spraying mode onto a metal strip passing through the segment. At least one speed sensor is installed in the segment to detect the speed of the metal strip passing through the segment. A controller is configured to select the spraying mode of the hybrid nozzles depending on the received speed of the metal strip, and control a pressure and a flow rate of the cooling water and air, respectively, to be supplied to the hybrid nozzles by controlling a cooling water supply and an air supply.
