Abstract

PURPOSE: To prevent oxidation of pouring molten metal and readily obtain sound tubular bodies by providing a gas flow curtain on the pouring side of an inclined metal mold in centrifugal casting and substituting the metal mold inside with an inert gas atmosphere.
CONSTITUTION: Prior to pouring of molten metal to the inclined type centrifugal casting machine, the inside of an inclined metal mold 1 is filled with inert gas such as N2 to maintain the metal mold 1 inside under the inert gas atmosphere. This atmosphere is maintained during pouring and even after the pouring. Even in the feed path of the molten metal to be poured from a ladle 3 to the metal mold 1, the chances for the molten metal to contact O2 are reduced. Namely, a shut-off device 4 by a gas flow curtain is disposed in opposition to the outside of the opening end on the pouring side of the metal mold 1. From this device 4, inert gas such as N2 is spouted through a nozzle 11 toward the opening opposing surface and the entry of the outside air into the metal mold 1 is prevented by the gas flow curtain 12 by this inert gas. As a result of this, the casting composed of the composite casting or the like integrated with both inside and outside layers sounder than conventional ones may be obtained.
