Constitutive properties of ice at Dye 3 Greenland

A method and apparatus for manufacturing a thin amorphous metal strip. Molten metal is injected onto a single cooling roll rotating at high speed. A gas flow impeding wall is disposed adjacent to the surface of a cooling roll and extends across the body of the cooling roll. The wall is located upstream of the molten metal injection nozzle. CO2 gas is jetted along one surface of the gas insulating wall which faces the molten metal injection nozzle and toward the surface of the cooling roll. An atmosphere rich in CO2 gas is maintained adjacent the roll surface just upstream of the molten metal injection nozzle.
