PENGARUH KONTROL PENUANGAN TERHADAP PEMBUATAN SILINDER PEJAL ALUMINIUM PADUAN HASIL PROSES DIRECT CHILL CASTING
ABSTRACT: Raw material of
Semi-Finished product which in form of solid cylinder used many in construction
workhouses, especially molding construction workshop specially unit making of
model (corn pattern). Elementary material of solid cylinder which is often
exploited for pattern is aluminum of mixed, with formed easy and light
consideration. One of so much process of manufacture able to produce raw
material of semi-finished product is Direct Chill Casting (DCC). In this
research is focused to lessen crudity of surface of product of DCC by control
infusion of metal dilution into printing; mould. Tunis used as media to control
infusion of metal dilution into printing; mould. Tunis controls the exit of
metal dilution arranged open stopper bar cover at hole of tunic. Time of
opening close bar of cork to control infusion of metal dilution in this
research is 9 second and 13 second. Each; Every variation of specimen control
infusion taken 3 and each specimen tested by value crudity of divided into
surface 3 area that is underside, middle and of specimen. Result of test
crudity of surface 3 the area is meant. Result of research indicate that
infusion control have an effect on to crudity of surface of product of DCC.
Control infusion with hole plug time of opening of tunic 9 second, assess
crudity of surface of product of DCC smaller 18.7% (5.53 µm) compared to value
crudity of product of DCC (6.8 µm) with hole plug time of opening of tunic 13
second.
