Abstract: Continuous casting apparatus comprising a plurality of compression units (11), each of which is defined by a lower roll (12) and an upper roll (13) configured to exert a compression action on a cast metal product (P). Each lower roll (12) defines with the respective upper roll (13) a passage gap (14) for the metal product (P). The passage gaps (14) of the compression units (11) are disposed aligned along a casting axis (Z) with an at least partly curved development. A straightening roll (15) is disposed on the extrados side of said casting axis (Z) and between at least two of the lower rolls (12).

Abstract: Apparatus to replace a guide unit in a continuous casting machine. A platform is positioned, during use, at the side of a casting line, and is provided with at least a first positioning zone of at least a first guide unit and at least a second positioning zone of at least a second guide unit. The platform is associated with a rotation device to take, on each occasion, the first positioning zone or the second positioning zone facing the side of the casting line. A movement device moves the second guide unit from a positioning zone outside the platform and, during use, in line with the casting line, to the second positioning zone of the platform and to move the first guide unit from the first positioning zone of the platform to the positioning zone outside the platform and, during use, in line with the casting line.

Abstract: In a continuous-casting plant, the segments of the guide for the casting bar are replaced rapidly, at least in part, using a two-station system, at least one of which stations being mobile, so as to be able to align head on a platform provided with means for hooking and extracting the said guide with the structure containing the guide itself. Once this alignment is obtained, the guide is displaced from one station to the other, its segments are replaced, and the guide is brought back into the original position.
