LIQUID-COOLED MOULD FOR CONTINUOUS CASTING OF STEEL BILLETS IN SLAB FORM

摘要

The invention concerns a liquid-cooled plate mold with adjustable width for the continuous casting of billets from steel in the form of slabs, particularly for a slab thickness of less than 100 mm. The shape-imparting broad side plates (1) and narrow side plates (2) of the ingot mold are constructed in the direction of their transverse extension so as to increase in cross section for the billet, while the narrow side plates (2) extend substantially parallel to one another along the height of the ingot mold. Further, the broad side plates (1) are constructed so as to be concave at least in a region (3) of smallest slab width in such a way that, in cross section, the apex height (13) of the ingot mold wall forming a curve has a determined height relative to a rectangle inserted in the drawing. The shape of the billet side plates at the billet outlet end (5) corresponds to the billet format to be produced.
