description PROBLEM TO BE SOLVED: To provide a centrifugal casting method by which a molten metal pouring tube is inserted without trouble into a cylindrical mold of a centrifugal molding device. SOLUTION: A belt-like laser beam that is emitted from a light emitting element 46 and received by a light receiving element 48 intersects at 90° with a belt-like laser beam that is emitted from a light emitting element 47 and received by a light receiving element 49, in a plane orthogonal to the axial line of a molten metal pouring tube 20. Then, the axial line of the pouring tube 20 under the assumption of no sagging occurring is set in a manner coinciding the center of a square detection region that is formed by the intersecting. If the pouring tube 20 is sagging by gravity, the center of the detection region is separated from the axial line of the pouring tube 20, which reduces a light quantity shut off by the pouring tube 20, with a received light quantity increased in the light receiving elements 48, 49. By distributing this increment of the received light quantity to the X direction component and the Y direction component, the position is known of the axial line of the pouring tube 20.
