Abstract
An example molten material funnel includes a first outlet lip and a second outlet lip. The first and second outlet lips are configured to both contact molten material communicated through the molten material funnel.
Claims18
A molten material funnel, comprising:
- a first outlet;
- and
- a second outlet, wherein the first and second outlets both face at least partially vertically upward such that an amount of molten material communicated through the molten material funnel impinges on both the first and second outlets, wherein at least one outlet comprises a replaceable sheet.
A molten material funnel, comprising:
- a first outlet;
- and
- a second outlet, wherein first and second outlets both face at least partially vertically upward such that an amount of molten material communicated through the molten material funnel impinges on both the first and second outlet,
- wherein at least one outlet comprises a replaceable sheet,
- wherein both the molten material funnel and replaceable sheet comprises a steel, a superalloy, a refractory metal, a ceramic or a hybrid material.
2 more elements
A casting assembly, comprising:
- a supply of molten material;
- a shot tube that communicates molten material to a die;
- and
- a funnel having a first outlet and a second outlet, the funnel configured to communicate molten material from the supply to the shot tube in a first direction such that an amount of the molten material impinges on both the first and second outlets, the first and second outlets facing at least partially in a second direction opposite the first direction, wherein at least one outlet comprises a removable plate.
1 more element
A method of communicating molten material, comprising:
- impinging a flow of molten material on a surface of a funnel prior to communicating the molten material to a die cavity, and using at least three distinct funnel orientations to communicate molten material to at least three distinct areas of a shot tube.
