Kind Code:

B2

Abstract:

To provide a centrifugal casting device where troughs are smoothly cooled over the whole length.SOLUTION: A centrifugal casting device has a process where a pair of troughs 20a, 20b are alternately inserted from one end to the other end in a mold, while rotating the mold around the shaft center thereof, the troughs and the mold are relatively moved in the lengthwise direction thereof, and molten metal is injected into the mold from the troughs inserted therein. When one trough gets out from the mold (Step1,4) and when the other trough gets in the mold (Step2,5), blacking liquids for deformation prevention are applied, respectively. By flowing (applying) the blacking liquids to one trough for two times, respectively, the cooling of the trough can be sufficiently performed. At this time, the application regarding one trough is performed at the time when it gets out from the mold and at the time when the other tough gets in the mold, thus trouble is not generated in the casting operation. Further, upon the application, when a frame 30 preventing the deformation of each trough is provided around the trough, the warpage of the trough can be prevented.SELECTED DRAWING: Figure 2
