Abstract
A surface of molten metal is covered with a polyphase mixture of a cryogenic fluid and at least one additional constituent in the form of particles, the particles having a size less than 50 microns and forming a homogeneous and stable suspension in the boiling liquefied gas. The particles may be metal or metal oxide or glass or carbon or vegetable or mineral oil, and serve to reduce radiative heat losses from the metal by reflection and/or to serve as a lubricant of the metal in a mold.
