Abstract
A method of continuously casting metal ingots is provided comprising the steps of introducing molten metal into an open-ended mold, applying a liquid cooling medium to the mold to effectuate at least partial solidication of the molten metal in the mold and advancing an ingot from the mold, with the ingot having the peripheral portion, at least, solidifed while applying liquid cooling medium to the exterior surface of the emerging ingot. The improvement of the present invention comprises retarding the cooling effect of the liquid cooling medium by mixing a gas with the medium to be applied to the ingot surface prior to application of the medium to the ingot surface, whereupon the gas forms a layer of gaseous insulation between the medium and the ingot surface upon application of the medium to the ingot surface.
