Abstract
This invention relates to a method of casting metal in a rotary mould or die under the protection of an inertizing atmosphere formed by a liquefied gas. In the mould or die, successive casting operations are performed with different metals while maintaining an infeed of liquefied gas during each of these casting operations and while the metal involved is solidifying, until an end product is obtained which is formed from a plurality of layers of different metals. The invention is applicable in particular, but not exclusively, to the production of centrifugally cast tubes and rolling-mill rolls.
