DOLU KALIP VE REPLİCAST CS YÖNTEMLERİ İLE DÖKÜMÜN ETİAL- 160 Al-Si ALAŞIMI İÇİN KARŞILAŞTIRILMASI

Full Mold and ReplicastCS casting methods have been used widely in producing aluminum, cast iron, bronze and steel castings. The most popular use of the Full Mold method places the refractory coated foam pattern in compacted unbonded sand and the the foam replaced by the liquid metal during pouring. In the full mold casting method, the carbon pickup, lap and fold defects can create an obstacle for the successful commercial applications. Therefore, other methods to allow foam patterns in casting production required. The alternative methods are the elimination of the foam pattern before pouring. In the Replicast CS method, foam patterns are covered with several layers of ceramic coating and then ceramic shell can be fired in order to eliminate the foam pattern from casting cavity. The ceramic shells are backed by compacted unbonded sand and pouring can be done. In this study, casting experiments of ETIAL 160 Al- Si alloy have been made by using Full mold and ReplicastCS methods.
