Exemplary embodiments of the invention provide a side dam for a continuous metal casting apparatus having elongated opposed casting surfaces forming a casting cavity. The side dam has an elongated upstream part and an elongated downstream part that are mutually laterally pivotable, and a smooth metal-contacting side surface extending continuously from an upstream end to a downstream end of the side dam. The surface has regions thereof formed on the upstream part and the downstream part. Mutual pivoting of the upstream part and the downstream part of the side dam enables the regions of the smooth metal-contacting side surface to be moved out of mutual coplanar alignment. The side dams can therefore be used to form either a convergent or divergent casting cavity to assists the casting procedure and to enhance the properties of the cast article.

Stationary side dam for continuous casting apparatus

A method of producing a clad metal ingot suitable for rolling to form a clad metal sheet, and the clad metal ingot so produced. The method involves providing a solid core ingot having an upper side with a rolling face thereon having cavities extending inwardly into the ingot from the rolling face. All or all-but-one of the cavities are blocked against molten metal entry and casting cores extending outwardly from the rolling surface are provided in alignment with the cavities. Molten cladding metal is cast on the rolling face around the casting cores to produce a composite ingot and the casting cores are removed to produce voids in the cladding layer, and the cavities are unblocked. The resulting interconnected cavities and voids are filled with a molten metal to form cast-in-place metal lugs keying or pinning the cladding layer to the core ingot.
