A method of casting a metal bath (2) to single ingots, where the bath is supplied into a preferably vertically positioned mould (1), in which the bath solidifies and is moulded to an ingot with a cross-sectional geometry substantially in agreement with the cross-sectional geometry of the mould, and where the bath is supplied, moulded and caused to solidify in a substantually tubular and thin-walled metal casing (1) constituting or comprised by said mould, which casing (1) is caused to follow along with the ingot in process steps subsequent to the casting, which casting is carried out intermittently as down-hill casting where bath in known manner is supplied at an upper portion of the mould, casing, or intermittently as up-hill casting where bath in known manner is supplied at a lower portion of the mould, casing. The method according to the invention is characterized especially in that said casing in process steps subsequent to the casting in a manner known per se is caused to be consumed and in a suitable process phase finally removed so as not to be included in products manufactured of the ingot, and the casing (1) is caused to be consumed instead of the ingot material inside thereof in order to increase the yield of the ingot material, and that a hot top (16) is provided externally against an upper portion (5, 15) of said casing (1). The invention also relates to an apparatus for carrying out the method. |
