Abstract
In order to unchoke the casting outlet of a vessel such as a casting ladle fitted with a casting tube for transferring molten metal to a tundish, a feed pipe is engaged in a lateral opening formed in the upper portion of the casting tube and guided within the tube until the end of the feed pipe opens in the vicinity of the casting outlet. The feed pipe is then connected to a supply of oxygen or similar oxidizing gas which is discharged in a jet onto the mass of solidified metal which obstructs the outlet. After the outlet has been cleared by melting of the mass of metal, the feed pipe is withdrawn and the lateral opening of the casting tube is sealed-off.
