The present invention relates to a rolling roll cooling apparatus of a steel making facility, and more particularly, to maximize the cooling efficiency of the rolling roll by supplying and circulating a cooling water maintained at a constant temperature in a loading rack where a plurality of rolling rolls are placed. The present invention relates to a rolling roll cooling apparatus of an iron making facility.

일반적으로 압연롤 냉각장치는 유지보수를 위한 압연롤을 작업의 편리성을 위해서 일정온도로 냉각시키기 위해서 사용된다.In general, the rolling roll cooling device is used to cool the rolling roll for maintenance to a certain temperature for the convenience of work.
