Abstract
The paper presents the optimization of master alloy amount for the high
nodular graphite yield (80-90%) in cast iron obtain in lost foam
process. The influence of the gating system configuration and the shape of the
reaction chamber, the degree of spheroidisation cast iron
was examined. Research has shown that the, optimal of master alloy amount of
1.5% by mass on casting iron. The degree
of spheroidisation is also influenced by the gating system configuration. The
best spheroidisation effect was obtained for liquid cast iron
was fed into the reaction chamber from the bottom and discharged from the top.
