Abstract (en)
[origin: ES8602460A1] A protective gas shield is formed around steel, to prevent oxidn. from the moment of pouring to the moment of solidification, by use of liq. and/or solid and/or gaseous carbon dioxide. - In ingot casting, the ingot mould is purged with carbon dioxide and the molten steel is teemed into the mould under the protection of a carbon dioxide shield such that the mould is filled with a carbon dioxide cover which covers the steel until it solidifies. In this embodiment, the carbon dioxide shield may be (partially) replaced by an argon shield. - In continuous casting, the molten stream is protected by carbon dioxide from the moment of formation until the moment it solidifies.
