Abstract
PURPOSE: To make fusion welding perfect and provide the sound and tightly integrated composite structure by substiting the atmosphere in a rotary mold with an inert gas atmosphere and pouring outside shell molten metal then pouring inside shell molten metal in succession.
CONSTITUTION: Shutters 6, 7 are disposed to both opening ends respectively of a rotary mold 1 to substitute the inside of the mold with an inert gas atmosphere without interfering with the rotation of the mold 1. While this atmosphere state is being maintained of the shut-off of the inside and outside by the inert gas flow curtains 16, 16 in the openings, outer shell molten metal is poured in the rotary mold 1 by way of a ladle 5 and spout 4, whereby the inside shell layer is centrifugally cast on the inside surface of the mold. At this time, the outside shell molten metal is prevented from oxidizing owing to the decrease in the oxygen density by the inert gas atmosphere until it freezes. Next, the inside shell molten metal is poured by way of another ladle 5 and spout 4 and therefore the inside shell layer perfectly adheres to the inside surface of the oxidation-prevented outer shell layer, whereby the perfectly integrated composite cylindrical casting is produced.
