Abstract: A trough for cooling and delivering molten metal to a casting station. The trough comprises a refractory portion for holding the molten metal and heat transfer means associated to external walls of the refractory portion for extracting heat from the molten metal. The heat transfer means may comprise a fluidized bed compartment for holding and fluidizing a fluidization material. Also, the heat transfer means may comprise a cooling jacket, an inner wall of the cooling jacket and the external walls of the refractory portion defining the fluidized bed compartment.

Abstract: A process of casting a molten metal to form a cast metal strip ingot while controlling heat flux from the cast metal. The process comprises continuously supplying molten metal to a casting cavity formed between a pair of moving continuous casting surfaces that withdraw heat from the molten metal to cause metal solidification, and continuously withdrawing a resulting cast strip ingot from the casting cavity. A gas (e.g. air) containing water vapour substantially without liquid water (i.e. a moist gas) is supplied to the inlet of the casting cavity in a region containing the meniscus formed where the molten metal first contacts the casting surfaces. The moist gas has the effect of adjusting the heat withdrawal by the casting surfaces to minimize surface defects in the cast strip ingot and to avoid undesired distortion of the casting cavity. Furthermore, in those cases where a parting agent is applied to the casting surfaces, the amount of parting agent applied to the casting surfaces may be reduced.
