ABSTRACT:
A method of continuous casting of ingots having a cross section with a high width to height or thickness ratio includes the steps of using a mold with a corresponding cross section and a casting pipe with bottom or near-bottom outlets and having laterally a minimum distance from the wall of the mold; preheating the casting pipe prior to casting to a temperature being at least approximately similar to the temperature of the metal later to be poured into the mold; initially closing the bottom outlet of the mold prior to startup; pouring molten metal into the mold for filling the mold up to a particular level while continuing heating the casting pipe; commencing withdrawal of an ingot from the mold along a curved path when the level of molten metal in the mold has reached the level of the outlet or outlets of the casting pipe.
