PURPOSE:To obtain hoop metal having exellent surface quality in supplying molten metal into a space at an upper place of rotating molds to produce the hoop metal by continuous casting, and surrounding surely a surface of the molten metal in an inert gas atmosphere with only a little inert gas consumption to prevent the surface of the molten metal from its oxidation. CONSTITUTION:A closed body 6 formed by refractory, such as steel plate or fireproof board, etc., is arranged on the rotating molds 1, 2 of twin belt type continuous casting machine or twin roll type continuous casting machine, and sliding touch part 5 made of fireproof board, such as ceramic board, etc., is arranged between the closed body 6 and the molds 1, 2, and then the inert gas, such as Ar, etc. is supplied from an introducing pipe 7. In this way, the molten metal is poured by the continuous casting under the inert gas atmosphere surely on its surface. |
