    摘要: The invention provides a method of reducing butt curl during DC casting of a metal ingot. The ingot is cast in at least two stages, including an initial casting stage and then a steady-state casting stage carried out at higher casting speed. The emerging ingot is cooled by directing a liquid coolant onto its outer surface. During the first casting stage, the liquid coolant is directed in the form of at least two streams, including a constant first stream in the form of a series of first jets, and an intermittent second stream in the form of a series of second jets. The first and second jets impact the outer surface at locations spaced from each other peripherally and/or longitudinally of the ingot. Both the first and second streams experience film boiling when they contact the ingot. The invention includes apparatus for the method.

    摘要: An exemplary embodiment of the invention provides a method of direct chill casting a composite metal ingot. The method involves sequentially casting two or more metal layers to form a composite ingot by supplying streams of molten metal to two or more casting chambers within a casting mold of a direct chill casting apparatus. Inlet temperatures of one or more of the streams of molten metal are monitored at a position adjacent to an inlet of a casting chamber fed with the stream, and the inlet temperatures are compared with a predetermined set temperature for the stream to determine if there is any difference. A casting variable that affects molten metal temperatures entering or within the casting chambers (e.g. casting speed) is then adjusted by an amount based on the difference of the compared temperatures to eliminate adverse casting effects caused by the difference of the inlet temperature and the set temperature. Preferably an adjustment is selected that causes the monitored temperature to approach the set temperature. Another exemplary embodiment provides equipment for operation of the method.
