ABSTRACT:
Apparatus for the continuous casting of metals, particularly of steel in curved path, in which in the initial portion of the curved path of the casting bar below the mold the bar-guiding means are missing. According to the invention, in the apparatus of this type the casting bar-guiding means provided only in the final portion of the curved path of the casting bar, upstream of the withdrawing and straightening mechanism, comprise at least one pair of powered pulling rollers arranged near their upper, or mold-facing end. To this apparatus there is associated a curved, rigid starter bar which is bent substantially to the same curvature as the curved path of the bar, and is of such a length that when it is positioned to close the mold outlet, it is still engaged between the first pair of powered pulling roller of the casting bar-guiding means provided in the last portion of the curved path of the casting bar, upstream of the withdrawing and straightening mechanism. The spacing between the several successive pairs of powered pulling rollers forming part of the casting bar-guiding means in the last portion of the casting bar curved path, and of the following withdrawing and straightening mechanism including the powered extractor roller pair at the outlet of said mechanism, does not exceed the length of the starter bar, so that the starter bar is always engaged by at least one powered pulling roller pair.
