<p>PURPOSE: A cooling apparatus is provided to intensively cool the semi-finished product in which coagulation is completed and then cause the grain size of the semi-finished product to be smaller, thereby increasing the strength of the semi-finished product. CONSTITUTION: A cooling apparatus includes a lower cooling part (110), an upper cooling part (120), and a cooling fluid supplying part (130). The lower cooling part is arranged between a pinch roll and a cutter, and has, therein, first and second lower cooling supports on which a plurality of coolant spraying nozzles and air spraying nozzles are mounted. First and second upper cooling supports on which a plurality of coolant spraying nozzles and air spraying nozzles are mounted are provided in the upper cooling part. The cooling fluid supplying part supplies cooling fluid to the lower and upper cooling parts, and cools the semi-finished product passing between the lower cooling part and the upper cooling part.</p> |
