PURPOSE:To maintain the surface of a cooling roll at an adequate temp. and to obtain an amorphous metal with less loss parts by ejecting another melt onto the surface of the roll prior to ejection of molten metal onto the roll. CONSTITUTION:A cooling roll 1 is kept rotated at a high speed and a melt 4 is ejected from the 1st nozzle 2 to maintain the surface of the roll 1 at an adequate temp. Molten metal 5 is ejected from the 2nd nozzle 3 upon ending of the ejection of the melt 4, whereby a light-gage strip of the amorphous metal is produced. The timing for ejecting the metal 5 is preferably right after the end of the ejection of the melt 4, and if the ejection delays long, the temp. on the surface of the roll 1 falls again below the adequate temp. |
