Centrifugal Casting Process Flashcards
What type of mould is used in centrifugal casting?
A permanent mould that is rotated during the solidification of the casting.
How is hollowness developed in centrifugal casting?
By rotating the die around the central axis of rotation, no core is needed.
Does centrifugal casting require a core for hollow parts?
No, it does not require a core.
Can centrifugal casting be used for both hollow and solid castings?
Yes, the axis of rotation will change depending on the type of casting.
What force acts continuously on the metal in centrifugal casting?
Centrifugal force.
What is the effect of centrifugal action on non-metallic inclusions and slag particles?
It segregates them near the center of rotation.
What types of parts are most suitable for centrifugal casting?
Cylindrical parts and pipes.
What type of solidification is promoted by centrifugal casting?
A: Directional solidification.
What are the three types of centrifugal casting?
True centrifugal casting, semi-centrifugal casting, and centrifuging or pressure casting.
Which type of centrifugal casting uses a central core to form the inner surface?
Centrifuging or pressure casting.
In centrifuging, what is the orientation of the axis of rotation?
The axis of rotation is always vertical.
What role does centrifugal force play in centrifuging or pressure casting?
It aids in the proper feeding of mould cavities.
What type of objects can be cast using semi-centrifugal casting?
Only symmetrical objects.
How are mould cavities filled in centrifuging or pressure casting?
They are filled under pressure from the centrifugal force of the metal.
Where are casting cavities located in centrifuging or pressure casting?
Around the outer portion of the mould.
