Abstract
A method and apparatus for centrifugal casting a blank separable into a plurality of preforms having a required configuration for forging to a finished component. Individual molds are symmetrically located around the axis of rotation of a casting table and have mold cavities that are filled by molten alloy under the centrifugal force created by rapidly rotating the table. Alternatively, a cylindrical mold is centered on the axis of rotation and the centrifugal force created by rapidly rotating the table causes the molten alloy to fill cavities in the wall of the mold. Centrifugal forces of at least 20 g may be employed.
Claims20
A method of manufacturing a forged metallic component comprising the steps of rotating casting means about an axis of rotation to generate a centrifugal casting force, feeding molten alloy to said rotating casting means for casting a plurality of elongate rectilinear blanks extending substantially parallel to and radially spaced from said axis of rotation, separating each of said blanks into a plurality of preforms having a required configuration for forging to a desired component, and forging each of said preforms to produce said component.
