Centrifugal casting machine and method of applying blacking liquid in the centrifugal casting machine

摘要

PROBLEM TO BE SOLVED: To provide a centrifugal casting apparatus for smoothly cooling a trough over its entire length. SOLUTION: A pair of troughs 20a and 20b are alternately inserted from one end to the other end of a mold, and the trough and the mold are relatively moved in the length direction while rotating the mold around its axis. In a centrifugal casting device that injects molten metal from a trough inserted into the mold, when one trough leaves the mold (Steps 1 and 4) and when another trough enters the mold (Steps 2 and 5). Apply a deformation prevention blacking solution to each. By flowing (applying) the blacking liquid twice to each trough, the trough can be sufficiently cooled. At this time, since the application for the one trough is when it comes out of the mold and when the other trough enters the mold, the casting operation is not hindered. Further, if a frame 30 for preventing deformation of the trough is provided around the trough at the time of application, warpage of the trough can be prevented. [Selection diagram] Fig. 2
