Abstract
Method and apparatus for use in hot top continuous casting of reactive metals, especially magnesium and magnesium containing alloys. To prevent oxidation a protective gas is supplied to the porous refractory hot top material (1) and eventual joints. It is arranged a closed chamber (7) between hot top (1) and a jacket (8) for supply of gas. It is preferred to use sulphur hexafluoride eventually in mixture with other gases.
