This invention relates to an extractor/straightener device for continuous metal casting installations, particularly for curved continuous casting. In order to cast either round-section strands and square-, rectangular- or polygonal-section strands, the extractor/straightener device (10) comprises two successive pairs of extractor rollers, one pair including rollers (11, 12) with a groove or race therein (15) for round-section strands (7'), the other pair including cylindrical rollers (13, 14) for square-section strands (7"). The two pairs of extractor rollers (11, 12 and 13, 14) are followed by a straightener roller (31). Means are provided to regulate the distance between the rollers (11, 12 and 13, 14) of each pair of extractor rollers so as to exert a tractive action on the strand (7' or 7"), alternately, by means of either the former or the latter pair of said rollers (11, 12 or 13, 14) depending upon the profile of said strand.
An extractor/straightener device for continuous metal casting installations, particularly for curved continuous casting, wherein the strand (7) which is cast in a substantially vertical direction, specifically through an open-ended curved mold (1), may have either a round-section or a square-, rectangular-, polygonal-section or the like, and it follows first a curved path of travel wherefrom it emerges to turn into a substantially horizontal direction by passing through said extractor/straightener device (10), characterized in that it comprises two successive pairs of extractor rollers, one pair including rollers (11, 12) with a groove or race therein (15) for round-section strands (7') and the other with cylindrical rollers (13, 14) for square-, rectangular-or polygonal-section strands (7"), these two pairs of extractor rollers (11, 12 and 13, 14) being followed by a straightener roller (31) and means being provided to regulate the distance between the rollers (11, 12 and 13, 14) of each pair of extractor rollers, such as to exert a tractive force on the strand (7' or 7") alternately by the former or the latter of said pairs of extractor rollers (11, 12 or 13, 14) depending upon the profile of said strand.
