Abstract
PURPOSE: To efficiently obtain the double flanged pipe of superior quality by using the core of low-melting-point metals for the centrifugally casting mold and performing centrifugal casting.
CONSTITUTION: After core-casting bands 2, 2 are mounted to a metal mold 1, pouring members are inserted into through-holes 2c and molten metal of small solidification shrinkage and low-melting-point metals is injected into the metal mold 1. Along with the rotation of the metal mold 1, a core 3 is centrifugally cast. Next, the bands 2, 2 are removed after waiting for the solidification, thence ordinary centrifugally casting bands 4, 4 are installed. Next, molten metal for double flanged pipe of a melting point higher than that of the core metal is pouring into the metal mold 1 where the core 3 exists and the double flanged pipe 5 provided with double flange parts 5b, 5b is cast through rotation. At the rapping, the core 3 is removed through melting or impact of the core metal by the solidification latent heat of the molten metal for pipe, whereby the double flanged pipe 5 is obtained.
