Abstract
|
|
|
Using 3 sort of sprue design, 2 sort of heat source and nickel-chromium alloy, sample of total 36 were constructed, The result of experimental was researched on casting porosity on metal alloy according to the sort of sprue design and that heat source.
The results were as follows :
1. The largest volume of casting porosity was direct sprue (closed type), the nest was runner bur type and were type.
2. The influence on casting porosity of sprue design was greater than heat source.
3. When the type of heat source were used oxygen-acetylene and induction method, the volume of casting porosity was little difference.
