Abstract
A continuous casting mold for casting relatively thin slab comprises a pair of broad walls and a pair of narrow walls. The narrow walls are movable inwardly and outwardly with respect to the mold cavity to adjust the width of the slab being cast. The broad walls in an upper portion of the mold are spaced farther apart to permit introduction of molten metal into the mold. The broad walls in the lower portion of the mold are substantially parallel to each other. The narrow mold walls are adapted to sealingly engage the broad mold walls and are wider in the upper portion of the mold than in the lower portion. In one embodiment, a tilt angle of the lower portion of the narrow walls is independently adjustable from that of the upper portion of the narrow walls while in a second embodiment, each of the walls comprises independently angled top and bottom portions and provides a flat and smooth surface to the contained molten metal. Solidification in the upper portion of the mold is substantially prevented.
