The present invention relates to a vertical centrifugal casting device comprising: an installation frame including a rotary table; a rotation table bearing-coupled to the rotary table so as to be rotated by the operation of a driving means; a supply connection means; rotation-preventing equipment; a mold part; a side mold fixing means; an upper mold fixing means; a connection fixing part; a lifting means; and an ejector means coupled to the lifting frame of the lifting means so as to eject a molded product.

A mold used for centrifugal casting includes a mold body formed in a cylindrical shape and a lid member (40) that is detachably assembled to an end part of the mold body in an axial direction. The lid member includes a lid body (41) that is attached to an opening part formed at the end part of the mold body, a protrusion part (450) that is fitted to the mold body, and a spring that applies elastic force to the lid body in a direction in which the lid body closely contacts the mold body.

A method for producing cast items in a casting method, wherein a charge of a conductive material is introduced into the sphere of influence of at least one alternating electromagnetic field, so that the charge is kept in a levitating state. The melt is poured into moulds in order to produce turbine blades, prostheses or turbocharger impellers.

Herein disclosed is a centrifugally cast pole having a substantially uniform wall thickness along the long axis of the pole. During centrifugal casting, molten metal is poured inside a rotating, tapered mold. As chilled liquid is poured over the outside of the rotating mold, the metal forms, or paints, to the contour of the mold interior creating a metal pole. By precisely controlling casting gyrations such as the spin, travel, pitch, and yaw of the rotating mold and the calibration and physical mechanisms of the casting machine, hollow, tapered, tubular metal poles are produced with previously unknown uniformity of wall thickness. The controlling principles, designs, and mechanisms of this centrifugal casting method enable wall uniformity to extremely high tolerances. By extension, the ability to precisely control the metal volume painted inside the mold allows, as a design choice, wall thickness variation in any embodiment if so desired.
