Abstract
PURPOSE: To prevent neck breaking and enable a sound double-flanged pipe to be obtained by building the split core dies built in with slits into centrifugally casting dies and retreating the slits to the circumferential direction at the freezing of molten metal.
CONSTITUTION: Split core dies 2 built in with split slits 3 are set in centrifugally casting dies 1 in such a manner that the inside surface of the slits 3 become flush to the inside surface of the dies 2. Next, when the dies 1 are rotated and molten metal is poured into the dies 2, the shrinkage by freezing of the molten metal begins. At this time, a cylinder member 4 is driven by way of a heat sensor 6 to retreat the slits 3 gradually from the central direction. Then, the shrinkage by freezing of the molten metal is controlled by the thickness of the slits 3 and the relieves 5 of the slits.
