Factors Impacting a Casting (5) Flashcards
1
Q
High-Temperature
A
- Causes rough finish
- Increased shrinkage
- Increased gas development
- Growth + weak structure
2
Q
Low-Temperature
A
Can cause Misruns and Cold-Shots
3
Q
High-Pour Rate
A
- Picks up gases and may oxidize the metal\
- Mold erosion causing loss of shape
- Cause Cold-Shots
4
Q
Low-Pour Rate
A
- Sections may freeze before fully filling the Mold
- May cause Cold-Shuts
5
Q
Progressive Solidification
A
Freezing of liquid; outside, in.
6
Q
Directional Solidification
A
Freezing of liquid; one part then another.
7
Q
Chill
A
Device made of metal inserted in the Mold to fasten solidification.
