<p>PURPOSE: A rolling roll cooling device of a steel manufacturing facility is provided to supply and circulate cooling water maintaining a constant temperature always inside a stacking stand in which a plurality of rolling rolls is stacked, thereby maximizing the efficiency of cooling the rolling rolls. CONSTITUTION: A rolling roll cooling device of a steel manufacturing facility includes a cooling water storage tank (200), a supply tank (230), a rolling roll stacking support (240), first and second opening valves (241,242), a chilling tank (300), a cooling pipe (330), a circulation pump (310), and a storage tank (320). The cooling water tank includes a cooling water recovery space (210) and a cooling water supply space (220). The supply pump supplies the cooling water stored inside the cooling water supply space to inside the rolling roll stacking support. The second opening valve supplies the cooling water circulating inside the rolling roll stacking support to the cooling water recovery space.</p> |
