PURPOSE: An apparatus for reducing continuous casting segment rolls is provided to prevent bulging of a strip by minimizing friction of sliding plates between reduction plates and reduction frames and effectively preventing raising of segment rolls so that roll gap between left and right segment rolls is constantly maintained. CONSTITUTION: In an apparatus for reducing continuous casting segment rolls which is installed in such a manner that segment rolls (R1,R2) through which molten steel flown into a mold through ladle and tundish passes apply a certain rolling reduction to molten steel between segment roll parts (R1',R2') mounted on frames (F1,F2), the apparatus comprises first and second sliding members which are installed so that the sliding members are moved to the lower side of a horizontal beam (B) of a stand (S) on the inner side of which the segment roll parts (R1',R2') are arranged by individual driving means(10a,10b); first and second reduction members(20a,20b) which are installed at the lower side of frames of the segment roll parts (R1',R2') so that the reduction members(20a,20b) are contacted with each other when the sliding members are moved, and on at least one of which an inclined region is formed to prevent lifting of the segment roll parts (R1',R2'); first and second gap adjusting means(30a,30b) which are installed between the frames of the segment roll parts (R1',R2') to adjust gap between the segment roll parts (R1',R2'); and an air ejection means(40) which is installed on the frames (F1,F2) of the roll parts to prevent foreign substance from sticking onto the reduction members contacted with the sliding members and onto contact regions of the gap adjusting means(30a,30b).
