摘要：The invention relates to a roll changing apparatus for rolling mills, by means of which seamless steel tubes or the like can be produced. The apparatus has a pair of guide girders (5a, 5b), which are arranged on a supporting block (3) and can be moved parallel to one another, a multiplicity of roll carriages (1a, 1b, ..., 1q), each of which has a set of roll rollers (13a, 14a), and a device for moving the roll carriages, in which two or more roll carriages are in each case arranged on the guide girders (5a, 5b) and at least one of the roll carriages (1a, ..., 1q) can be moved forwards on the respective guide girder (5a or 5b respectively) to form a rolling mill. If the roll carriages are to be changed, the roll carriages (1a, ..., 1q) which have been moved forwards are moved backwards on the guide girders and the other roll carriages (1b, ..., 1p) are then moved forwards in order in this way to achieve an automatic changeover of the roll carriages within a short time. <IMAGE>
