Abstract
PURPOSE: To obtain an ingot of adequate rolling temp. by automatically controlling the secondary cooling of the ingot and intensely cooling only the preset cutting position locally.
CONSTITUTION: A cutting position A is set so as to obtain an ingot of a prescribed length by the count signal, etc. for the number of revolutions of roller of a roller apron 3 in the process when the ingot continuously drawn from a cooling mold 1 passes a secondary cooling zone 3 while being cooled, and spary nozzles 5 are so designed as to be changeable to two steps, strong and weak, alternately or overall. The spray system is so arranged that with respect to the movement of the ingot 2 it is normally subjected to secondary cooling with the weak spray and the spray nozzles 5 of the place where the cutting position passes are successively changed over to stronger sprays so that only the cutting position is locally cooled intensely, and this is controlled automatically. Hence, at the point of time when cutting is started, the cutting part locally solidifies down to the central part of the ingot.
