PROBLEM TO BE SOLVED: To obtain a casting with fine structure and uniform quality across entire thickness direction by making the casting speed of a thick portion as a specific range and inclining a ladle from data of the molten metal remaining quantity in the ladle and the casting speed. SOLUTION: In this centrifugal casting, casting speed is set to be 7-40 kg/see. It is preferable that a thick portion of at least 10 mm or more from the inner face of a centrifugal casting mold is cast at the casting speed of 7-40 kg/see. At that time, a computer 2 is installed in a control chamber 21. The computer 2 stores the measuring data inputted via a receiving device 3 at given time intervals by a processing program, and outputs the data to a display 5 in real time. Additionally, the required molten metal volume and the ladle metal remaining quantity against the casting elapsed time are computed at given time intervals from a preset data such as the casting speed inputted from a keyboard 4. The results are stored as the indication data and displayed on the display 5. The ladle 11 is inclined by the indication data so as to keep a given casting speed.
