Abstract
A centrifugal casting apparatus comprising an upper portion into which molten material is poured, the upper portion having a central rotational axis about which the apparatus is rotated; at least one block runner is connected to the upper portion at the proximal end of the block runner and to at least one mould at the distal end of the block runner, the block runner being mounted substantially perpendicular to the axis of rotation; and wherein the moulds are oriented substantially parallel to the axis of rotation of the centrifugal casting apparatus.
Claims11
A method of casting a component comprising:
- attaching a mould to a centrifugal casting apparatus, such that the mould is oriented substantially parallel to an axis of rotation of the centrifugal casting apparatus, and
- applying a molten feedstock through (i) an upper portion of the centrifugal casting apparatus, a central rotational axis of the upper portion coinciding with the axis of rotation of the centrifugal casting apparatus, and (ii) a block runner mounted substantially perpendicular to the axis of rotation to control and contain a turbulence within the molten feedstock,
- wherein the molten feedstock is a titanium aluminide alloy material,
- a thinnest part of the mould is oriented in a radial direction away from the axis of rotation,
- the thinnest part of the mould is a radial outermost part of the mould, and
- the component is a blade.
