چکیده
|
The mold-filling behavior in the casting of aluminum alloy (a413) using lost foam casting (lfc) was explored. the effects of gate numbers, type of gating and casting thickness on the fdling behavior were evaluated. although, unlike convectional casting process, the gating system showed little effect on fdling ability, casting thickness created a greater effect on the mold fdling. in contrast with convectional casting process, the mold fdling seems to be controlled by casting geometry as a consequence of combined influence of heat and mass transfer. the melt used to enter from the first gate instead of last gate which is in contrast with convectional casting process
