PURPOSE:To form a continuously cast thin sheet having an excellent surface characteristic by supplying a specified amt. of casting powder by a specified flow rate of inert gas into a sealing chamber of a two drum system continuous casting device for the thin metallic sheet. CONSTITUTION:A molten metal 4 is supplied by a nozzle from a tundish 5 into the sealing chamber 6 constituted of water-cooled drums 1, 1 and a refractory gate 2. The casting powder 7 for holding the temp. of the molten metal is supplied from a supply box 8 onto the surface of the molten metal 4. The inert gas such as Ar or N is passed at the specified flow rate to a casting powder supply pipe 9 and the powder 7 in the bos 8 is supplied by each specified atm. onto the surface of the molten metal 4 by such gas. Since the supply rate of the powder 7 is constant, the molten metal 4 is maintained always at the specified temp. The atmosphere on the surface of the molten metal is made non-oxidizing by the inert gas to prevent the formation of the defective continuously cast thin sheet 3 by the change of the molten metal temp. or oxidation. |
