Definitions
- the invention relates to a method for centrifugal casting according to the preamble of claim 1.
- a method for centrifugal casting is known for example from US-A-2 763 041.
- the melt shows the tendency at the beginning of the casting process to spread in the mold in the form of a "snake” or spiral from the pouring end to the other end of the mold. This spiral leaves traces in the cast structure of the finished pipe that one would like to avoid.
- a periodically varying rotational speed is superimposed on the basic rotational speed, the frequency and / or amplitude of which can preferably be controlled as a function of time or another parameter.
