Abstract
The invention relates to a method and apparatus for controlling the temperatures of a plurality of zones of a casting hearth or vessel. The invention also relates to a method for controlling the thickness of the solidified skull of castable material in the casting hearth or vessel. By the present invention, the efficiency of the skull casting process can be significantly improved by reducing the thickness of the skull and thereby increasing the amount of castable material which can remain molten and pourable.
